Yield: 95%

Reaction Conditions:

with hydrogen;triethylamine;palladium on activated charcoal in methanol at 20; for 24 h;Inert atmosphere;

Steps:

14
5 to 6 : Compound 5 (3.67 g, 11.69 mmol) was dissolved in methanol (100 mL) and Et₃N(3.0 mL). 10% Pd/C (0.40 g) was added to the solution. The mixture was stirred at room temperature under H₂ for 24 h. The solution was filtrated though Celite. The solvent was removed by evaporation and dried under vacuum to give light yellow oil 6 (2.10 g, 95%)
