Reaction Conditions

Reaction Steps

A flask containing tetrahydrofuran (2.0 mL) was charged with sodium amide (152 mg, 3.69 mmol; Aldrich) and chilled to 0° C. (4-Fluorophenyl)hydrazine hydrochloride (400 mg, 2.64 mmol; Aldrich) was added in portions. After 5 minutes, the solid had completely dissolved and the ice bath was removed. Stirring was continued for 1 hour, then the solution was chilled again in an ice bath and 1-(bromomethyl)-2,3-difluoro-4-methylbenzene (598 mg, 2.72 mmol; Aldrich) was added dropwise. After 30 minutes, the ice bath was removed and the reaction was heated to 50° C. overnight. The mixture was diluted with water (5 mL) and extracted with dichloromethane (2×10 mL). The combined organic extracts were dried over magnesium sulfate, filtered, and concentrated in vacuo to afford the title product which was carried on without further purification: LC/MS (DCI/NH3) m/z 250 (M+H−NH3)+.
