Procedure

A mixture of 4-(6-trifluoromethyl-benzo[b]thiophen-3-yl)-piperidine-1-carboxylic acid methyl ester (3.1 g, 9.0 mmol) in HBr (45 mL, 30% in acetic acid) was stirred at room temperature for 20 hours when the volatiles were removed in vacuo. The residue was washed with EtOAc and the product was collected by filtration yielding 3.09 g (94%) of the desired product as a white solid.
