52% | With triethylamine; at 20℃; for 1.5h; | Step C: Methyl 3-[(2,6-difluorophenyl)carbonyl]amino}-4-fluorobenzoate; To a solution of <strong>[369-26-6]methyl 3-amino-4-fluorobenzoate</strong> (5.5 g, 33 mmol) in DCM (100 ml_) was added TEA (6.8 ml_, 49 mmol) and 2,6-difluorobenzoyl chloride (4.3 ml_, 34 mmol). After 90 min at rt, the reaction mixture was washed with H2O and concentrated to a brown oil. The product was purified by column chromatography (eluting with 30-60percent EtOAc /hexanes) to generate the desired product in 52percent yield (5.37 g, 17 mmol). MS (ESI) m/z = 310 [M+Hf . |
