Reaction Conditions

Reaction Steps

Triethylamine (23 ml) was added to a suspension of 3-nitro-4-methylaniline (0.8 g), 4-cyanobenzoyl chloride (13.1 g), 4-dimethylaminopyridine (0.8 g) in methylene chloride (200 ml) which had been cooled to 0° C. The reaction mixture was allowed to warm to ambient temperature and was stirred for 5 hours. The mixture was partitioned between methylene chloride and 0.5M hydrochloric acid solution. The organic phase was dried over magnesium sulphate, filtered and evaporated to dryness. The residue was triturated under isohexane and the resulting solid was isolated and dried under vacuum at 55° C. to yield N-(4-methyl-3-nitrophenyl)-4-cyanobenzamide (18.3 g); NMR: 2.5 (s, 3H), 7.49 (d, 1H), 7.96 (m, 1H), 8.05 (d, 2H), 8.12 (d, 2H), 8.51 (d, 1H), 10.77 (s, 1H).
