実験手順
Hydrazine hydrate (520 μL, 10.9 mmol) was added to a solution of the ester (780 mg, 2.18 mmol) of Example 9 in ethanol (25 ml) and the resulting mixture was heated under reflux for 18 hours. After cooling, the precipitate was collected by filtration and washed with ether (50 ml) to afford the title compound (550 g) as a white solid, m.p.>250° C.
