실험 절차

To a solution of 4-methylpiperidine-1,4-dicarboxylic acid mono-tert-butyl ester (229 mg, 0.94 mmol) in DMF (10 mL) were added DIPEA (0.493 mL, 2.83 mmol), pyrrolidine (0.118 mL, 1.41 mmol) and HATU (537 mg, 1.41 mmol). The reaction mixture was stirred at room temperature for 18 hours and then partitioned between water and EtOAc. The organic layer was separated and washed with a 0.1N aqueous HCl solution and brine, dried over Na2SO4, filtered and concentrated to give 4-Methyl-4-(pyrrolidine-1-carbonyl)piperidine-1-carboxylic acid tert-butyl ester as a white solid (279 mg, 100%). LCMS (Method H): RT 4.00 min; [M+Na]+ 319
