実験手順

A mixture of 1,1-dimethoxyacetone (5.00 ml), benzylmercaptan (5.50 ml), nitromethane (23 ml), ethylenediamine (3.00 ml) and acetonitrile (15 ml) was stirred at room temperature, and then overnight at 80° C. The reaction mixture was concentrated, and the obtained residue was subjected to silica gel column chromatography to give the title compound (5.81 g, yield 48%) as a colorless oil from a fraction eluted with ethyl acetate-hexane (1:6, volume ratio).
