Reaction Steps
Through a solution of tert-butyl 4-(5-cyanopyridin-2-yl)piperidine-1-carboxylate (compound 50.2, 200 mg, 0.70 mmol, 1.00 equiv) in ethyl acetate (20 mL) was bubbled HCl gas. The resulting mixture was stirred for 40 min at 5-10° C. The resulting precipitate was collected by filtration and dried to yield 150 mg (97%) of the title compound as a white solid.
