实验过程

To a solution of methyl N-[[2-chloro-5-[3-(dimethylamino)-1-oxo-2-propen-1-yl]phenyl]methyl]carbamate (i.e. the product of Step A) (4.14 g, 13.9 mmol) in methanol (80 mL) was added hydrazine hydrate (0.771 g, 15.4 mmol). The reaction mixture was stirred at room temperature for 2 days. The reaction mixture was filtered and the solid collected was dried under reduced pressure to provide the title compound, a compound of the present invention, as a solid (3.26 g).
