Reaction Steps
TFA (0.75 mL, 9.735 mmol) was added to a solution of tert-butyl N-[4-(1-methyl-2-oxo-4-piperidyl)-3-pyridyl]carbamate (74 mg, 0.2423 mmol) in DCM (2 mL) and was stirred at ambient temperature for 2 hours. The reaction mixture was adsorbed onto a pre-wetted (methanol/DCM (1:1), 2 mL) SCX-2 cartridge (2 g) and flushed with DCM/methanol (1:1, 20 mL) and then the basic components eluted with 2 M ammonia in methanol (20 mL). The basic eluent was evaporated to dryness to afford 4-(3-aminopyridin-4-yl)-1-methylpiperidin-2-one as a pale yellow oil (50 mg, 97%). MS (ES+) 206.1.
