Participants

Reaction Steps

HCl gas was passed through a solution of 6 g (1 eq.) tert-butyloxycarbonyl-4-(dimethylamino)-4-(thiophen-2-yl)piperidine in 120 ml chloroform at 0° C. for 1 h. The reaction course was monitored by thin-layer chromatography (75% EtOAc/hexane). Once the conversion was complete, the solvent was removed under reduced pressure and 5.3 g (98%) of product were obtained in the form of a white solid.
