Reaction Steps

Methyl 2-(6-(trifluoromethyl)pyridin-3-yl)piperidine-4-carboxylate hydrochloride (3 g, 9.24 mmol) was dissolved in DCM (50 mL) and DIPEA (4.03 mL, 23.10 mmol). Methyl carbonochloridate (1.019 mL, 12.93 mmol) was added dropwise to the solution. The mixture was stirred at room temperature for 10 minutes. The mixture was washed with 0.1 M HCl (2×100 mL) and satd NaHCO3 (100 mL), then dried through a phase-separator and evaporated yielding crude dimethyl 2-(6-(trifluoromethyl)pyridin-3-yl)piperidine-1,4-dicarboxylate (3 g, 94%) as a dark brown oil.
