Procedure

The title compound of Step C was dissolved in 100 mL of dry tetrahydrofuran and cooled to 0° C. Then 1,1-dimethylhydrazine (2.3 g, 38.2 mmol) was added at 0° C. The resultant mixture was stirred at room temperature overnight. The reaction mixture was concentrated under reduced pressure, diluted with water, extracted twice with methylene chloride and the combined extracts were dried (MgSO4). The organic solution was then concentrated under reduced pressure to yield the title compound of Step D as a brown solid which was carried on entirely in Step E.
