85% | With triethylamine; In methanol; at 20℃; for 24h; | General procedure: The appropriate glycine ester hydrochloride (17.7 mol) and Et3N (2.2mL, 17.7 mol) were added to a solution of 2-hydroxybenzophenone (1; 3.5 g, 17.7 mmol) in MeOH (10 mL), and the solution was stirred atr.t. for 24 h. The mixture was then concentrated in vacuo and acetone was added. The precipitated Et3N·HCl was collected by filtration and washed with acetone. The filtrate was evaporated to dryness, and the product was crystallized from MeOH (for 2a,b) or from DCM-hexanes (for 2c). Important The recovered 2-hydroxybenzophenone (1) could be repeatedly used to prepare the initial product 2 (for recovery method, see below). |
