Procedure
To a mixture of 2-amino-5-chloro-benzoic acid (0.82 g, 4.80 mmol) in Dowtherm A (20 mL), was added the compound of Step A (1.0 g, 4.80 mmol). The mixture was warmed to reflux for 15 hours, then cooled to room temperature. Upon cooling, a white precipitate formed which was collected by filtration. The solid was triturated with diisopropyl ether followed by methylene chloride to give the title compound (0.58 g, 45%), m.p. 296-302° C. Anal. calcd. for C16H12CINO: C, 71.25; H, 4.48; N, 5.19. Found: C, 70.92; H, 4.44; N, 5.04.
