Yield: 66%
Reaction Conditions:
with hydrazine in ethanol at 60; for 3 h;
Steps:
1.1 Step 1: Preparation of intermediate 1b
(4.5 g, 43 mmol) was dissolved in absolute ethanol (250 ml) and stirred at 60 ° C for 3 h. The solvent was distilled off under reduced pressure and saturated sodium bicarbonate solution (50 ml) was added to a solid completely dissolved,The extracted organic phase was removed by evaporation under reduced pressure to give the white solid Ib (6.3 g, yield 66%) which was used in the next step without further purification.
