98% | In dimethyl sulfoxide at 120℃; for 19h; Inert atmosphere; | 1,4-Dimethoxy-2-(trifluoromethyl)benzene [0454] To a flame dried round-bottom flask, backfilled with argon gas, containing a solution a solution of No.8 sodium methoxide (40.52 g, 750 mmol) in anhydrous degassed No.3 DMSO (150 mL) was added No.8 1-fluoro-4-methoxy-2-(trifluromethyl)benzene (14.56 g, 75 mmol). The reaction was stirred at 120°C. for 19 h until full consumption of starting material was observed by NMR. The reaction was quenched with No.8 ice H2O (700 mL) and organics were extracted with Et2O (3200 mL). The combined organic phases were washed with H2O (2200 mL), followed by brine (200 mL), then dried over MgSO4, filtered and concentrated in vacuo to give the desired No.8 dimethoxy benzene as a clear No.8 oil. The oil crystalized into a solid over the course of several days and was of sufficiently high purity to use without further purification (15.21 g, 98%).
