実験手順

A mixture of 182 mg of 2-ethoxy-4-oxo-2,3,4,5,6,7-hexahydrocoumarone and 1 ml of benzylamine was heated in a glass tube at 110° C. for 12 hours. The reaction mixture was purified by column chromatography on silica gel using a solvent mixture of ethyl acetate and n-hexane (1:1) to give 126 mg of N-benzyl-4-oxo-4,5,6,7-tetrahydroindole as white crystals (yield 56%). ##STR21##
