Reaction Steps

A solution of 7a (160 mg, 0.300 mmol) and hydrazine hydrate (286 μL, 9.18 mmol) in ethanol:toluene (2.70 mL of an 8:1 mixture, respectively) was heated to 100° C. in a sealed microwave vial for 10 min, An additional aliquot of hydrazine hydrate (200 μL, 6.42 mmol) was added, and the resulting mixture was heated to 135° C. in a sealed microwave vial for 15 min. The reaction mixture was cooled to rt and partitioned between EtOAc and water. The combined organics were washed with water and brine, dried (sodium sulfate) and concentrated in vacuo to afford the title compound 9a. m/z (ES) 523 (MH)+.
