Procedure

After adding methanol (30 ml) and 2N aqueous sodium hydroxide (10 ml) to methyl 4-(4-chloro-3-nitrophenoxy)-7-methoxy-6-quinolinecarboxylate (1.00 g, 2.57 mmol), the mixture was stirred at 60° C. for 1 hour. The reaction solution was allowed to cool to room temperature, 2N hydrochloric acid was added for neutralization, the methanol was distilled off, and the precipitated light brown crystals were filtered out, thoroughly washed with water and dried at 70° C. to obtain the title compound (897 mg, 2.39 mmol, 93.1%).
