Yield:59820-84-7 100%
Reaction Conditions:
with palladium 10% on activated carbon;hydrogen in methanol at 20;Inert atmosphere;
Steps:
23
At room temperature, compound 23-3 (1 g, 5.12 mmol) was dissolved in methanol (20 mL), and 10% palladium on carbon (0.1 g, 10% w/w) was added, Stir overnight at room temperature under nitrogen atmosphere. TLC monitors the reaction. After the completion of the reaction, the reaction solution was suction filtered through Celite, and the filtrate was concentrated to dryness.Compound 23-4 (1g) was obtained as a dark red oil, which was reconstituted with DCM (2mL), and a white solid precipitated when PE (10mL) was added.After being concentrated to dryness, it became a lavender solid with a yield of 100%.
