実験手順

To 100 ml of thionyl chloride was added 26 g of 3-(1-acetylpiperidin-4-yl)propionic acid, obtained in Reference Example 1-(2), in small portions with ice-cooling. The mixture was stirred for 5 minutes, after which the excess thionyl chloride was distilled off and the solid residue was washed with diethyl ether to give 26.4 g of 3-(1-acetylpiperidin-4-yl)propionyl chloride as a pale yellow powder.
