Into a reactor, 40 g of p-bromophenol and 200 ml of DMF (dimethylformamide) were charged, to which 10 g of a 60% NaH (sodium hydride) were gradually added to give a solution. To the solution, 18 g of methoxymethyl chloride were added dropwise with stirring at a temperature of 30° C. or lower, and reacted overnight at room temperature to give a reaction solution. The reaction solution was poured into water, extracted with benzene, washed with water, dried over sodium sulfate anhydride, and thereafter the solvent was evaporated and the residue was distilled under reduced pressure to give 38.4 g (Y., 79.3%) of 4-bromopheny methoxymethyl ether. b.p.; 65°-67° C./0.6 mmHg GC; 99.4%
