反应详情

To a solution of 2,6-bis(1,1-dimethylethyl)-4-(methylthio)phenol (1.16 g, 4.6 mmole) in dimethylformamide (15 ml) was added sodium hydroxide (0.37 g, 9.2 mmole). After the solution was warmed for one hour, methyl iodide (0.72 g, 5.1 mmole) was added, and the mixture was warmed for an additional three hours. The reaction mixture was poured into water (150 ml) and extracted with diethyl ether (180 ml in three positions). The ether extract was washed with saturated aqueous sodium carbonate, dried over sodium sulfate, filtered, and concentrated in vacuo to an oil. Upon standing the oil crystallized. Recrystallization from hexane gave the title compound, m.p. 50°-52°.
