Reaction Steps

Methyl 2-(4-chloro-3,5-difluorophenyl)piperidine-4-carboxylate hydrochloride (1.82 g, 5.58 mmol) was dissolved in dichloromethane (50 mL). DIPEA (2.430 mL, 13.95 mmol) and methyl carbonochloridate (0.527 mL, 6.70 mmol) were added and the mixture was stirred at room temperature for 3 h. 0.1 M HCl was added and the aqueous layer was extracted with DCM. The combined organic layers were filtered through a phase separator and evaporated to yield dimethyl 2-(4-chloro-3,5-difluorophenyl)piperidine-1,4-dicarboxylate (1.83 g, 94%). MS m/z 348 (M+H)+
