Reaction Conditions

Reaction Steps

In 1 ml of N,N-dimethylacetamide was dissolved 0.2 g of the 2-(2-carboxyphenyl)-6-methyl-4-quinolinecarboxylic acid obtained in Example 2 and heated at 180° C. for 1 hour. Then the reaction mixture was poured into water, made alkaline by adding sodium carbonate and washed with dichloromethane. The aqueous layer was neutralized with 3M hydrochloric acid until a precipitate was formed. After extracting with dichloromethane, 60 mg of 2-(6-methylquinolin-2-yl)benzoic acid was obtained. NMR (270 MHz, CD3OD): δ 7.58-8.32 (m,9H); 2.58 (s,3H).
