A 19.9 g (0.1 mol) portion of o-methylbenzoyl bromide was added dropwise with cooling to a mixture of 13.7 g (0.1 mol) of o-ethoxyaniline and 8.4 g (0.1 mol) of sodium bicarbonate in 200 ml of acetone with stirring. After addition of the o-methylbenzoyl bromide, the reaction mixture was warmed to 40° C and the mixture was refluxed and stirred for another 40 hours. After filtering, the ether was distilled from the reaction mixture and the residual material was re-dissolved in ether and washed with water. The ether layer was dried over anhydrous sodium sulfate, the ether was removed and the product was distilled to obtain 24.1 g (94.5%) of a clear pink liquid having a boiling point of 148° C/0.04 mm Hg and nD20 of 1.5929.
