Hydrochloric Acid → 4-(2-(Methylsulfonyl)phenoxy)piperidine hydrochloride

Participants

Reaction Steps

To 4-(2-methanesulfonyl-phenoxy)-piperidine-1-carboxylic acid tert-butyl ester (2.6 g, 7.3 mmol) was added HCl in dioxane solution (4M) (15 mL). The reaction mixture was stirred at RT for 5 h. After completion of the reaction (monitored by TLC), the excess dioxane was removed in vacuo affording an off white solid. The crude material was washed with diethyl ether (3×20 mL) to afford 4-(2-(methylsulfonyl)phenoxy)piperidine hydrochloride (1.3 g, 80.7%).
