Methyl 4-[(biphenyl-2-carbonyl)-amino]-benzoate → 4-[(2-phenylbenzoyl)amino]benzoic Acid

Participants

Reaction Steps

A 3.15 g sample of methyl 4-[([1,1'-biphenyl]-2-carbonyl)amino]benzoate is refluxed for 8 hours in 100 ml of ethyl alcohol and 2.5 ml of 10N sodium hydroxide. The cooled reaction mixture is acidified with [[? acid]] and the desired product collected and dried to give 2.9 g of the desired product as a solid m.p. 246°-249° C. M+H=318.
