Yield: 90%
Reaction Conditions:
with palladium 10% on activated carbon;hydrogen in methanol at 20; for 2 h;Inert atmosphere;
Steps:
2 Step-2: Synthesis of Compound 3
10% Palladium charcoal (lOmmol) and dry Methanol (10 vol) were placed in a50 mL flask, and then compound- 2 (10 mmol) was added while stirring. Flushed with nitrogen and followed by hydrogen gas. Reaction left for stirring vigorously at room temperature for 2.0 h at hydrogen atmosphere, on completion the reaction mixture was filtered over celite and washed with methanol. The organic layer was evaporated and residue was dissolved in ethyl acetate, and was washed with water. The organic layers were dried over sodium sulfate, filtered and evaporated to yield compound-3 (yield: 90%).
