Route of Synthesis (ROS)
Route of Synthesis (ROS) of Amino-PEG8-acid CAS 756526-04-2
| Conditions | Yield |
| With palladium 10% on activated carbon; hydrogen In ethanol at 20℃; under 750.075 Torr; for 16h; | 93% |
| Experimental Procedure General procedure: To a solution of the appropriate azido compound s10a-c (1 eq.) in absolute ethanol, 10% Pd/C (0.05 eq) wasadded. The suspension was degassed under vacuum and purged with hydrogen three times then stirred at roomtemperature under hydrogen atmosphere (1 bar) for 16 h. The reaction mixture was filtered through a pad ofCelite 545, the filtrate was evaporated under reduced pressure to afford the expected compounds 5a-c whichwas engaged in the next step without further purification. |
