[step 2] 3-(Methylthio)-2-nitroaniline (1.0 g, 5.4 mmol) obtained in step 1 was dissolved in DMA (5.4 mL), pyridine (0.44 mL, 5.4 mmol) and 2-methoxyacetyl chloride (1.49 mL, 16 mmol) were added, and the mixture was stirred at room temperature for 2 hr. To the reaction solution were added methanol and aqueous ammonia, and the mixture was stirred at room temperature for 30 min. Water was added, and the crystals were collected by filtration, and dried to give 2-methoxy-N-[3-(methylthio)-2-nitrophenyl]acetamide (1.26 g, 91%).
