PROCEDURE

实验过程

147 g N-BOC-glutamin (t-butyloxycarbonyl-glutamin), 77 g benzylchloride and 4 g benzylbromide were refluxed in 600 ml tetrahydrofuran for 2.5 hours in the presence of a 5% excess of diazabicycloundecene. After the removal of the solvent, the residue was taken up in water-ethylacetate and washed with citric acid, sodium bicarbonate and water. Evaporating of the solvent and recrystallization from ethylacetate-hexane gave 120 g white crystals.
