Reaction Steps

Into a 250-mL round-bottom flask, was placed methyl 4-fluoro-3-nitrobenzoate (15.4 g, 77.78 mmol, 1.00 equiv), N,N-dimethylformamide (100 mL), methyl 2-amino-2-(4-fluorophenyl)acetate hydrochloride (20.4 g, 93.15 mmol, 1.20 equiv), and DIEA (50.2 g, 389.15 mmol, 5.00 equiv). The reaction was stirred overnight at 35° C. in an oil bath. The resulting solution was diluted with 500 ml of H2O and the resulting solids were collected by filtration. This resulted in 15 g (53%) of methyl 4-(1-(4-fluorophenyl)-2-methoxy-2-oxoethylamino)-3-nitrobenzoate as a yellow solid.
