Reaction Conditions:
with hydrazine hydrate in ethanol; for 16 h;Reflux;
Steps:
1.3 Step 3. Synthesis of 3-(trifluoromethoxy)benzohydrazide:
A mixture of ethyl 3-(trifluoromethoxy)benzoate (1.0 g, 4.27 mmol), hydrazine hydrate (5.0 mL) in ethanol (EtOH) (50.0 mL) was heated at reflux for 16 h. The mixture was concentrated under vacuum to give 3-(trifluoromethoxy)benzohydrazide (0.9 g, yield 96%). MS (ESI) calcd for C8H7F3N2O2: 220.05.
