Hydrochloric Acid → tert-Butyl 5-(benzyloxy)-6-methyl-2-(piperidin-4-ylmethyl)pyrimidine-4-carboxylate hydrochloride

Participants

Reaction Steps

tert-Butyl 5-(benzyloxy)-2-{[1-(tert-butoxycarbonyl)piperidin-4-yl]methyl}-6-methylpyrimidine-4-carboxylate (4.4 g, 8.8 mmol) was dissolved in ethyl acetate (44 mL), and a solution of hydrogen chloride in ethyl acetate (4 M, 68 mL, 270 mmol) was added, followed by stirring at room temperature for 3 hours. Hexane (100 mL) and ethyl acetate (100 mL) were added to the reaction solution, whereby a solid was deposited. The resulting solid was collected by filtration, and dried under reduced pressure to afford the title compound (3.7 g, 8.5 mmol) as a white solid (yield 95%).
