To avoid the preparation of cesium carbonate salt in hydromethanolic solution, we developed an alternative procedure: cesium carbonate (0.853 g, 2.63 mmol) was added to Boc-Asn (0.205 g, 0.88 mmol) in 5 mL of DMF. The mixture was stirred for 2 days at room temperature to complete the salt formation. Then benzyl bromide (42 μL, 2.2 mmol) was added. After stirring for 6 h at room temperature, the same treatment was applied. 1-Benzyl-3-Bocaminosuccinimide 1a, was isolated in a similar yield.
