Reaction Conditions:
with hydrazine hydrate in methanol; for 5 h;Reflux;
Steps:
4.7 General procedure for the preparation of 5-8
General procedure: A solution of 25-28 (3.08g, 0.01mol) and hydrazine hydrate (2.00g, 0.04mol) in methanol (50mL) was stirred under reflux for 5h. The solvent was evaporated under reduced pressure, and the residue was recrystallized from MeOH-H2O (9:1).
