Data are presented seeing that means SEM, = 3 mice per group. Conclusion We possess discovered that the 12 herein.1 Hz, 2H), 2.57C2.66 (m, 2H), 2.68C2.93 (m, 2H), 3.77 (s, 3 H), 4.17 (d, 12.1 Hz, 2H), 4.62 (s, 2H), 7.07C7.13 (m, 2H), 7.23C7.27 (m, 2H); MS (APCI) M+ = 339.9. 2-(Methylamino)-2-oxoethyl 4-(4-chlorophenethyl)piperidine-1-carboxylate (SA-57) To a remedy of carbamate 3 (1.2 g, 3.5 mmol) in DMSO (15 mL) was added methylamine (17.7 mL of the 2 M tetrahydrofuran (THF) remedy, 35 mmol, 10 equiv). 12.1 Hz, 2H), 4.62 (s, 2H), 7.07C7.13 (m, 2H), 7.23C7.27 (m, 2H); MS (APCI) M+ = 339.9. 2-(Methylamino)-2-oxoethyl 4-(4-chlorophenethyl)piperidine-1-carboxylate (SA-57) To a remedy of carbamate 3 (1.2 g, 3.5 mmol) in DMSO (15 mL) was added methylamine (17.7 Vitamin E Acetate mL of the 2 M tetrahydrofuran (THF) solution, 35 mmol, 10 equiv). The response vessel was covered, and the perfect Rabbit polyclonal to OLFM2 solution is was stirred at space temp for 5 times. The response was partitioned between drinking water and MTBE, as well as the organic coating was dried out Vitamin E Acetate over MgSO4, filtered, and focused. The ensuing residue was purified by silica gel chromatography (EtOAc) to supply SA-57 like a white solid (0.989 g, 83%). 1H NMR (400 MHz, CDCl3) 1.19 (qd, = 12.3, 4.5 Hz, 2 H), 1.41C1.53 (m, 1 H), 1.54C1.62 (m, 2 H), Vitamin E Acetate 1.77 (d, = 12.5 Hz, 2 H), 2.57C2.67 (m, 2 H), 2.70C2.86 (m, 2 H), 2.88 (d, = 4.9 Hz, 3 H), 4.04C4.27 (m, 2 H), 4.52C4.69 (m, 2 H), 6.06 (bs, 1 H), 7.07C7.14 (m, 2 H), 7.23C7.27 (m, 2 H); 13C NMR (100 MHz, CDCl3) 25.9, 31.7, 32.1, 32.2, 35.2, 38.0, 44.4, 64.2, 128.5, 129.6, 131.5, 140.6, 154.0, 168.7; MS (APCI) M+ = 338.9. 2-(Methylamino)-2-oxoethyl 4-(4-((triethylsilyl)ethynyl)phenethyl)piperidine-1-carboxylate SA-57 (590 mg, 1.74 mmol, 1 equiv), bis(acetonitrile)palladium(II) chloride (23 mg, 0.087 mmol, 0.05 equiv), X-Phos (85 mg, 0.174 mmol, 0.1 equiv), and Cs2CO3 (851 mg, 2.61 mmol, 1.5 equiv) were put into a 50 mL round-bottom flask. The vessel was evacuated and backfilled with N2 (3). Acetonitrile (10 mL) was added as well as the blend stirred for 25 min at space temp. Triethylsilylacetylene (0.468 mL, 2.61 mmol, 1.5 equiv) was put into the mixture, as well as the reaction was heated to 85 C for 4 h and stirred at room temperature overnight. The blend was partitioned between EtOAc Vitamin E Acetate and water. The organic coating Vitamin E Acetate was dried out over MgSO4, filtered, and focused. The ensuing residue was purified by silica gel chromatography (50% EtOAc in heptane to 100% EtOAc) to supply the title substance like a tan solid (690 mg, 89%). 1H NMR (400 MHz, CDCl3) 0.68 (q, 6 H), 1.05 (t, 7.9 Hz, 9 H), 1.19 (qd, 12.3, 4.5 Hz, 2 H), 1.41C1.53 (m, 1 H), 1.54C1.62 (m, 2 H), 1.77 (d, 12.5 Hz, 2 H), 2.57C2.67 (m, 2 H), 2.70C2.86 (m, 2 H), 2.88 (d, 4.9 Hz, 3 H), 4.04C4.27 (m, 2 H), 4.52C4.69 (m, 2 H), 6.06 (bs, 1 H), 7.07C7.14 (m, 2 H), 7.38C7.42 (m, 2 H); MS (APCI) M+ = 443.2. 2-(Methylamino)-2-oxoethyl 4-(4-ethynylphenethyl)piperidine-1-carboxylate (SA-57yne) 2-(Methylamino)-2-oxoethyl 4-(4-((triethylsilyl)ethynyl)phenethyl)piperidine-1-carboxylate (690 mg, 1.56 mmol, 1.0 equiv) was dissolved in THF (10 mL) and cooled within an snow shower. TBAF (1.72 mL of just one 1.0 M solution in THF, 1.72 mmol, 1.1 equiv) was added, as well as the response was stirred at 0 C for 1 h. The blend was partitioned between drinking water and EtOAc. The organic coating was dried out over MgSO4, filtered, and focused. The ensuing residue was purified by silica gel chromatography (20% acetone in heptane to 50% acetone in heptane) to supply SA-57yne like a white solid (194 mg, 38%). 1H NMR (400 MHz, CDCl3) 1.12C1.26 (m, 1 H), 1.39C1.53 (m, 1 H), 1.55C1.64 (m, 1 H), 1.77 (d, 11.5 Hz, 1 H), 2.61C2.71 (m, 1 H), 2.72C2.86 (m, 1 H), 2.88 (d, 5.1 Hz, 1 H), 3.05 (s, 1 H), 4.03C4.26 (m, 2 H), 4.49C4.67 (m, 2 H), 6.06 (bs, 1 H), 7.13 (d, 8.2 Hz, 1 H), 7.42 (d, 7.8 Hz, 1 H); 13C NMR (150 MHz, CDCl3) 25.9, 31.6, 32.1, 32.8, 35.2, 37.8, 44.4, 64.2, 76.7, 83.6, 119.5, 128.3, 132.2, 143.2, 154.0, 168.7; MS (APCI) M+ = 328.8.
