Yield:53936-56-4 100%
Reaction Conditions:
with 5%-palladium/activated carbon;hydrogen in ethanol at 20; under 3000.3 Torr; for 3 h;Autoclave;
Steps:
[Synthesis of Compound (9-3)]
To a 1-liter autoclave, 56.3 g (198 mmol) of the compound (9-2), 2.8 g of a catalyst (5% Pd/C), and 250 ml of ethanol were added. The resulting mixture was reacted at room temperature for 3 hours while the hydrogen pressure was maintained to be 0.4 MPa. After the catalyst had been removed by filtration, vacuum concentration was performed. Hereby, 38.5 g of the compound (9-3) was prepared (quantitative)
