Hydrazine → 2-(4-Bromophenoxy)acetohydrazide

Participants

Reaction Steps

To a solution of (4-bromophenoxy)acetic acid (1.0 g, 4.3 mmol) in THF (15 mL) was added N,N-Carbonyldiimidazole (0.84 g, 5.2 mmol). After refluxing for 2 hours, hydrazine (0.6 g, 20 mmol) was added to the reaction mixture slowly with a syringe at 0° C. The reaction mixture was allowed to warm to room temperature slowly and then concentrated to yield the desired product as a white solid. LCMS calculated for C8H10BrN2O2 (M+H): 245.0; found: 244.9, 246.9.
