To the solution was added 4-t-butylbenzylisothiocyanate (330 mg) and the mixture was stirred at room temperature for 12 hours. The resulting mixture was filtered under reduced pressure and the solvent was removed therefrom. The residue was purified by column-chromatography (ethyl acetate/hexane=1/2) to yield the compound 33-4 (253 mg, 48%) as a solid.
