실험 절차
3.8 g (18.4 mmol, purity 90%) of the compound from Example 20A are initially charged in 12.5 ml of ethanol. 8.9 ml (9.2 g, 183.8 mmol) of hydrazine hydrate are added, and the mixture is reacted in a single-mode microwave oven (CEM Explorer) at 170° C. (100 Watt) for 2 h. The reaction solution is then concentrated, and the residue is taken up in ethyl acetate and washed in each case once with saturated sodium bicarbonate solution and saturated sodium chloride solution. The organic phase is dried over sodium sulfate, filtered and concentrated under reduced pressure.
