Participants

Reaction Steps

To a stirred solution of N-(4-methoxyphenyl)-2,4-diaminobenzamide (19 g, 73.8 mmol) in N,N-dimethylformamide (250 mL) was added pyridine (6.6 mL, 81 mmol), followed by acetic anhydride (6.6 mL, 70 mmol). After stirring overnight, the solvents were removed in vacuo and the residue was chromatographed over a silica gel (10% tetrahydrofuran/90% chloroform). The appropriate fractions were combined and concentrated in vacuo to give 5.3 g (24%) of the title compound as an off-white solid.
