実験手順

Added to 4.28 g of ethyl phenylglyoxylate were 9.12 g of 4-amino-1-benzylpiperidine. The mixture was heated and stirred at 120° C. for 3 hours on an oil bath. Thereafter, ethanol formed was distilled off under reduced pressure, and the residue was purified by column chromatography on silica gel, thereby obtaining 6.3 g (yield: 81.4%) of N-(1-benzyl-4-piperidinyl)phenyl-glyoxylic acid amide.
