61.2 g of 3-hydroxy-4-nitrotoluene, 66.3 g of potassium carbonate, and 54.7 ml of benzyl chloride are heated in 800 ml of dimethylformamide to 100° C. for 1.5 hours; after cooling, the mixture is poured into water, and the thus-precipitated material is recrystallized from ethanol, yielding 82.0 g of 3-benzyloxy-4-nitrotoluene, mp 49°-51° C.
