Participants

Reaction Steps

A solution of the phthalimide 9-2 (3.05 g, 9.05 mmol) in EtOH (50 mL) was treated with hydrazine (2.84 mL, 90.5 mmol) and heated to 500C for 1 hour. The mixture was cooled, methyl t-butylether (100 mL) added, stirred for 1 hour and filtered. The filtrate was concentrated in vacuo to give the desired product 9-3 which was used in Step D without further purification.
