Reaction Steps
The crude material from Step 3 was dissolved in ethylene glycol (600 mL) and KOH pellets (125 g) and anhydrous hydrazine (36 mL) were added. The reaction was heated to 150° C. for 2 hr, then cooled to RT (room temperature) and diluted with 10% NH4OAc buffer (1.5 L) and the product was extracted into EtOAc. The crude product was chromatographed on silica gel (5% EtOAc/toluene) to yield the title compound, which was recrystallized in ether/hexane.
