実験手順

Methylthioisocyanate (210 mg) was dissolved in anhydrous dichloromethane (5 ml). To the solution were added N-triphenylmethylcysteamine (1.00 g: 1.1 molar equivalent) while cooling with ice. The reaction solution was stirred at room temperature for 30 minutes and was concentrated under reduced pressure. The residue was dissolved in chloroform (50 ml) and well washed with water and a saturated solution of sodium chloride. The chloroform layer was dried by using anhydrous sodium sulfate and concentrated under reduced pressure. The residue was purified by silica gel chroomatography using a solvent system of hexane/ethyl acetae (5:1 v/v) to obtain the desired substance (0.89 g) with a yield of 79%.
