Hydrazine hydrate (1.25 mL, 25 mmol) was added to a stirred suspension of methyl [(4-morpholin-4-ylphenyl)amino](oxo)acetate (intermediate 1, 6.6 g, 25 mmol) in methanol (150 mL). The reaction was heated to 75° C. for 2 h during which time the precipitate thickened. After cooling the precipitate was filtered and washed with diethyl ether (50 mL) and dried to give the title compound (6.32 g, 94%):
