7 g | With 5%-palladium/activated carbon; hydrogen In methanol at 20℃; for 45 h; | Intermediate 444 (7. 1 g, 28.9 mmol ) was taken up into methanol ( 100 niL and then 5percent Pd/C (0.7 g. ) was added. The mixture was hydrogenated at room temperature for 48 hours under (50 Psi) atmosphere. The mixture was filtered and the filtrate was evaporated under vacuum to obtain intermediate 445 ( 7 g ) as a white solid. |
