実験手順

A solution of sodium hydroxide (0.44 g, 11 mmol) in water (10 ml) was added to 2-iodo-5-cyanobenzoic acid methyl ester (2.7 g, 9.4 mmol) in methanol. The mixture was stirred for 20 h, then most of the solvent was evaporated and the residue acidified with 2N hydrochloric acid. The resulting precipitate was filtered off and dried to give a white solid (1.7 g). MS (−CI) m/z 272 [M-H]+.
