실험 절차

A 250-mL round-bottomed flask was charged with a solution of benzyl 3-(1H-imidazol-2-yl)piperidine-1-carboxylate (1.5 g, 5.26 mmol, 1.00 equiv) in dioxane (15 mL). To this was added conc. HCl (9 mL). The resulting mixture was stirred for 4 hours at 70° C. in an oil bath. The reaction progress was monitored by TLC (DCM: MeOH=10:1). Upon completion, the resulting solution was diluted with dioxane (10 mL) and concentrated on a rotary evaporator affording 3-(1H-imidazol-2-yl)piperidine hydrochloride as black solid in (0.48 g, 57%).
