Water → 3-(Trifluoromethyl)-4-isopropoxynitrobenzene

참여 물질

반응 단계

A solution of 41 g of sodium isopropoxide in 300 ml of dimethyl sulfoxide was added drop-by-drop to a chilled (5° C.) solution of 118 g of 2-chloro-5-nitrobenzotrifluoride in 100 ml of dimethyl sulfoxide. The resulting mixture was stirred at room temperature for one hour, poured into water, and the resulting mixture was extracted with ether. The extract was washed with water, dried, and the solvent was evaporated. The liquid residue was taken up in hexane and the solution was chilled to give a solid, which on recrystallization from hexane gave 2-isopropoxy-5-nitrobenzotrifluoride (2A), as a white crystalline solid, mp: 34°-36° C.
