5,6-Dihydroxyindole → Di(trimethylsilyloxy]indole

참여 물질

반응 단계

To 0.81 g (0.004 mole) of N,O-bis(trimethylsilyl) acetamide is added, stirring at room temperature, 0.3 g (0.002 mole) of 5,6-dihydroxy indole. When dissolution is completed, 2 ml dichloromethane are added and the solution is passed through a column of silica 60, eluating with dichloromethane. The first fraction obtained is concentrated in a rotavapor, then vacuum-dried. Thus are obtained 0.42 g (yield: 71%) of white crytal of 5,6[di(trimethylsilyloxy]indole.
