Procedure
75 g (0.347 mol) of 2-nitrobenzyl bromide, 37 g (0.342 mol) of o-cresol and 56 g (0.405 mol) of potassium carbonate in 500 ml of dimethylformamide is stirred for 5 hours at room temperature (20° C.). The reaction mixture is diluted with water and the aqueous phase is extracted three times with ether. The ether phase is dried and evaporated down. The crystalline residue is stirred with methanol and suction filtered. There is obtained 73 g (0.300 mol=88%) of the title compound as a colorless solid.
