Reaction Steps

A solution of the product of part (i) (3.80 g) and hydrazine hydrate (6.0 ml) in isopropanol (20 ml) was heated under reflux for 2.5 hours and then evaporated. Water was added to the residue and the mixture was extracted several times with dichloromethane. The combined extracts were washed with brine and dried (MgSO4). Evaporation of the solvent gave the title compound (3.30 g) as an amorphous foam which was used directly in the next stage.
