Reaction Steps
A mixture of tetrahydro-4H-pyran-4-one (10.3 g), benzylmercaptan (25.6 g), nitromethane (62.8 g), ethylenediamine (6.18 g) and acetonitrile (150 ml) was heated overnight under reflux. The reaction mixture was concentrated, and the obtained residue was subjected to silica gel column chromatography to give the title compound (17.6 g, yield 67%) as colorless crystals from a fraction eluted with ethyl acetate-hexane (3:1, volume ratio).
