実験手順

To a solution of 2-amino-4-iodobenzoic acid (2.5 g, 9.50 mmol) in DMF (10 mL) at rt under argon were added EDCI (2.18 g, 11.40 mmol), 1-hydroxybenzotriazole (1.54 g, 11.40 mmol), DIEA (1.98 mL, 11.40 mmol), and ammonia (7.0 N solution in MeOH, 1.90 mL, 13.30 mmol). The dark solution was stirred at rt overnight and diluted with H2O until precipitate formed. The precipitate was separated by filtration, washed with H2O, and dried under high vacuum for several hours to afford 2-amino-4-iodobenzamide as a tan solid (1.3 g, 52%). LC-MS (ESI) m/z 263 (M+H)+.
