Versuchsvorschrift
To a solution of 3-(1-benzyl-piperidin-4-yl)-6-trifluoromethyl-benzo[b]thiophene-2-carboxylic acid methyl ester (5.9 g, 13.6 mmol) in DCM (50 mL) was added methyl chloroformate (1.26 mL, 16.3 mmol) drop-wise. The resulting solution was stirred overnight when the volatiles were removed in vacuo. The residue was washed with heptane to yield 4.2 g (77%) of the desired product as a white solid.
