Reaction Conditions

Reaction Steps

A mixture of 1-(2-chloro-4-fluorophenoxy)-2-propanone (i.e. the product of Step A) (1.40 g, 6.93 mmol) and N,N-dimethylformamide dimethyl acetal (1.38 mL, 10.4 mmol) was heated to 90° C. for 3 h, and then concentrated under reduced pressure. The resulting material was diluted with ethanol (15 mL), and then methylhydrazine (0.49 mL, 9.0 mmol) and acetic acid (0.1 mL) were added. After 15 h, the reaction mixture was concentrated under reduced pressure and the resulting material was purified by silica gel column chromatography (5 to 40% gradient of ethyl acetate in hexanes as eluant) to provide the title compound as a brown yellow oil (680 mg).
