Procedure

A mixture of compound (G) (5.00 g), hydrazine hydrate (4.12 g), K2CO3 (7.00 g) and diethylene glycol (16 ml) were heated to reflux temperature for 1 hour. The condenser was exchanged by a distillation device and the mixture was distilled at 220-230° C. The distillate was extracted with MTBE and the organic phase washed with water and brine, dried (MgSO4) and concentrated in vacuo. The residue was purified by chromatography to yield a colorless oil (4.4 g).
