Reaction Steps

To a solution of 4 (1.6 g) in 25 ml of ethanol was added acetic hydrazide (0.4 g) and 2 drops of concentrated HCl. The resulting solution was heated to reflux for 3 hours. The solvent was removed under reduced pressure. The residue was treated with NaHCO3, and extracted with ethyl acetate. The combined organic phase was washed with brine, dried over Na2SO4. Removal of the solvent gave the desired product (1.25 g).
