Water-soluble Condensation Reagent Typical Procedure: To a 50 mL round bottom flask equipped with a magnetic stir bar and septum is added 1-(3-Dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride 2.54 g (13.3 mmol), 4-dimethylaminopyridine 1.62 g (13.3 mmol), carboxylic acid 1.02 g (2.46 mmol), alcohol 0.96 g (3.98 mmol) and CHCl3 (15 mL), and the reaction mixture is stirred at room temperature for 2.5 days. Acetic acid (0.5 mL) is added and the reaction mixture is stirred for 10 min to convert excess alcohol to a more easily separable acetate. The mixture is washed with saturated aqueous NH4Cl solution, diluted with Et2O, and the layers are dried, filtered and concentrated under reduced pressure. The crude material is chromatographed by silica gel column chromatography (hexane：ethyl acetate = 9：1) to give the desired product 1.25 g (1.96 mmol, 80%). |
