Reaction Steps

Hydrazinecarbothioamide (6.8 g, 75 mmol) was added to a solution of 4-bromo-2-fluorobenzoyl chloride (11.8 g, 50.0 mmol) in THF (50 mL) at rt and stirred for 1 hour. The reaction mixture was concentrated to give 2-(4-bromo-2-fluorobenzoyl)-hydrazinecarbothioamide as a white solid, which was used directly in the next step without purification. MS (ESI): mass calcd. for C8H7BFN3OS, 290.95, m/z found, 292.1 [M+H]+.
