実験手順

A solution of 4-methyl-4-(pyrrolidine-1-carbonyl)piperidine-1-carboxylic acid tert-butyl ester (296 mg, 1.0 mmol) in TFA (5 mL), DCM (5 mL) and water (0.1 mL) was stirred at room temperature for 2 hours and then concentrated under reduced pressure. The residue was taken up in MeOH and and loaded onto an Isolute® SCX-2 cartridge (10 g). The cartridge was washed with MeOH and the desired product was eluted with 2M NH3 in MeOH. The solvents were removed to give the desired product as a white solid (196 mg, 66%). LCMS (Method A): RT 0.31 min; [M+H]+ 197
