Procedure

HCl gas was passed through a solution of 1.5 g (1 eq) tert-butyl 3-(4-(dimethylamino)-4-(thiophen-2-yl)piperidin-1-yl)propyl(methyl)carbamate in 30 ml chloroform at 0° C. for ˜30 min. The reaction course was monitored by thin-layer chromatography (20% MeOH/CHCl3). Once the conversion was complete, the solvent was removed under reduced pressure. After trituration with diethyl ether, 1.5 g (98%) of product were obtained in the form of a white solid.
