Reaction Steps

6-Methylthio-7,8-dihydroxy-1-phenyl-2,3,4,5-tetrahydro-1H-3-benzazepine (5 g) is oxidized with 2,3-dichloro-4,5-dicyano-1,4-benzoquinone in methanol at room temperature as in Example 1 to give 6-methylthio-1-phenyl-2,3,4,5-tetrahydro-1H-3-benzazepine-7,8-dione which (1 g) is reacted with methylmercaptan in methanol to give 6,9-dimethylthio-7,8-dihydroxy-1-phenyl-2,3,4,5-tetrahydro-1H-3-benzazepine.
