실험 절차

To a solution of 2-(2-oxo-3,3-diphenylpiperidin-1-yl)acetic acid (Example 68E, 0.31 g, 1 mmol), tert-butyl piperidin-4-ylcarbamate (CAS 73874-95-0, 0.2 g, 1 mmol) and 2-(1H-benzo[d][1,2,3]triazol-1-yl)-1,1,3,3-tetramethylisouronium hexafluorophosphate(V) (0.38 g, 1 mmol) in dichloromethane (10 mL) was added diisopropylethylamine (0.7 mL), and the reaction mixture was stirred at room temperature overnight. The reaction mixture was then diluted with dichloromethane and washed with sequentially with 20 mL of 1 N HCl, water, 20 ml, of 1 N NaOH, and water. The organic phase was dried over magnesium sulfate and concentrated in vacuo to yield the title compound. 1H NMR (300 MHz, CDCl3) δ ppm 7.33 (m, 8H), 7.21 (m, 2H), 4.45 (m, 2H), 4.03 (m, 1H), 3.77 (m, 1H), 3.49 (m, 2H), 3.11 (m, 1H), 2.79 (m, 1H), 2.63 (m, 2H), 1.97 (m, 2H), 1.83 (m, 2H), 1.45 (m, 9H), 1.32 (m, 2H).
