実験手順

A solution of methanesulfonyl chloride 0.374 g, 3.3 mmol in ethyl acetate (3 ml was added to a mixture of 1-(2-hydroxyethyl)-4-methoxycarbonyl-4-(N'-phenylpropionamido)piperidine (1.0 g, 3 mmol) and triethylamine. The resulting mixture was stirred overnight. The reaction mixture was filtered and the filtrate was concentrated under vacuum to give an oily residue. The residue was chromatographed on silica gel (290 g; ethyl acetate/hexane: 1:4) to yield 1-(2-methanesulfonylethyl)-4-methoxycarbonyl-4-(N'-phenyl-propionamido)piperidine (0.53 g, 43%) as an oil.
