Participants

Reaction Steps

Methyl 2-(4-fluorophenyl)piperidine-4-carboxylate (7.4 g, 31.19 mmol) was dissolved in DCM (100 mL) and DIPEA (6.52 mL, 37.43 mmol) added followed by methyl chloroformate (2.95 mL, 37.43 mmol) at 0° C. The solution was stirred at room temperature for 1 h. The reaction mixture washed with 0.1 M HCl and satd NaHCO3. The organic phase was passed through a phase separator and evaporated to yield dimethyl 2-(4-fluorophenyl)piperidine-1,4-dicarboxylate (8.07 g, 97%) as a brown oil. MS m/z 296 (M+H)+
