To a stirred solution of 2,5-difluorobenzothioamide (22.5 g, 129.7 mmol) in EtOH (150 mL) was added hydrazine (6.1 mL, 194.5 mmol). After stirring at room temperature for 30 min, reaction was complete by LC/MS and white solid precipitated. The precipitate was filtered and washed with Hexanes to afford 2,5-difluorobenzimidohydrazide (5.52 g, 94%).
