Reaction Steps

The compound of Example 22 (50 mg) and 30 mg of methyl thioisocyanate were dissolved in 1 ml of pyridine. After 2 hours of stirring at room temperature, the solvent was distilled off under reduced pressure. The residue was purified by silica gel column chromatography (elution solvent; hexane:ethyl acetate=1:2) to obtain 42 mg of the title compound. Its physical properties are shown below.
