4-Benzoylbenzoic acid → HCID 10297752, compound

Participants

Reaction Steps

330 mg of benzophenone-4-carboxylic acid are dissolved in 6 ml of dichloromethane, then 283 mg of N-(3-dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride, 18 mg of 4-dimethylaminopyridine and 222 mg of ethyldiisopropylamine are added, and stirred for 20 minutes at room temperature. 300 mg of 2-amino-2-methyl-3-(2-trifluoromethylphenoxy)-propionitrile are subsequently added, and the mixture stirred for a further 40 hours. Afterwards, the mixed solution is washed with an aqueous sodium bicarbonate solution, then with a 1 n hydrochloric acid solution and finally with a saturated sodium chloride solution. The organic phase is then separated, dried with sodium sulphate, filtered and concentrated by evaporation. After recrystallisation in diethylether, the residue yields 372 mg of the title compound with a melting point of 121-123° C.
