Reaction Steps

HCl gas was passed through a solution of 10 g (1 eq.) tert-butyloxycarbonyl-4-(dimethylamino)-4-(thiophen-2-yl)piperidine in chloroform at 0° C. for ±1 h. Once the conversion was complete, 200 ml water were added to the reaction mixture, it was adjusted to a pH of ˜8 with Na2CO3 and then extracted with 15% IPA/CHCl3. The combined organic phases were dried over Na2SO4. Following removal of the solvent under reduced pressure, 6 g (89%) of product were obtained in the form of a white solid.
