Reaction Conditions:

with palladium 10% on activated carbon;hydrogen in ethanol; under 760.051 Torr; for 5 h;

Steps:

1.4 4) Synthesis of i

h (8g, 25.70mmol), palladium on carbon (1.37g, content 10%) was added to 50mL of ethanol, and stirred under normal atmosphere for 5h under hydrogen atmosphere. After the reaction was completed, palladium carbon was removed by filtration, and the filtrate was evaporated to dryness to obtain i ( 6.5g); yield: 89.91%,
