Participants

Reaction Steps

To a solution of 1,1-dimethylethyl 4-(4-formyl-2-thiazolyl)-1-piperidinecarboxylate (1.0 g, 3.4 mmol) in dichloromethane (20 mL) was added a solution of hydrogen chloride in diethyl ether (2.0 mL, 15 ml, 30 mmol). The reaction mixture was stirred under nitrogen at room temperature for 2 h and then evaporated under reduced pressure to give 1.2 g of the title compound as a white solid.
