Procedure

Methyl N-(4-chlorophenyl)-4-nitroisophthalamate (220 mg) obtained in step A was dissolved in 10 mL of a methanol solution of 7 mols of ammonia. After the reactor was sealed, the solution was heated for 36 hours at 80° C. with stirring. The reaction mixture was concentrated under reduced pressure, and the residue was purified by silica gel column chromatography. The resulting solid was dried under reduced pressure to obtain 48 mg (23%) of 4-nitro-3-N-(4-chlorophenyl)-isophthalamide.
