実験手順

(1H-pyrrol-2-yl)methylamine hydrochloride (60 mg) prepared according to the same procedure as described in Step 2 was dissolved in dichloromethane (2 ml) and to the solution was added 4-t-butylbenzylisothiocyanate (155 mg), followed by stirring at room temperature for 1 hour. The resulting mixture was concentrated under reduced pressure and the obtained residue was column-chromatographed (ethyl acetate/hexane=1/3) to yield the compound 17-1 (120 mg, 65%).
