Procedure

N-(5-Chloro-4-methoxy-2-nitrophenyl)acetamide (8.0 g, Reference Example 32(i) was added to a solution of sodium methoxide (2.0 g, 0.037 mole) in methanol (150 mL) and the mixture was stirred at ambient temperature for 4 hours. The reaction mixture was added to ice water (750 mL), stirred for 15 minutes and the aqueous mixture was filtered. The precipitate was washed with water and dried at 60° C. under vacuum to give 5-chloro-4-methoxy-2-nitrophenylamine (6.52 g) as an orange solid, mp 128-129° C. (i) 4-Methoxy-5-methyl-2-nitro-phenylamine
