実験手順
Methyl magnesium iodide prepared from reaction of magnesium (2.4 g) and methyl iodide (13.9 g) in absolute ether is dissolved in absolute benzene (50 ml) and a solution of 4-formyl-2,3,4,9-tetrahydrothiopyrano[2,3-b]indole (5.5 g) in absolute benzene (60 ml) is added dropwise thereto during 3 hours. The mixture is stirred at room temperature for 1 hour, poured slowly into an ice water containing ammonium chloride (10 g) and extracted with ether. The extract is evaporated. The oily residue is chromatographed on a column of silica gel and eluted with ether-benzene (1:50). The eluate is evaporated. The residue is again chromatographed on a column of silica gel and eluted with benzene and ether-benzene (1:20). The title compound is obtained from the latter eluate as an oil (4.58 g).
