75% | With benzotriazol-1-yloxyl-tris-(pyrrolidino)-phosphonium hexafluorophosphate; N-ethyl-N,N-diisopropylamine; In N,N-dimethyl-formamide; at 20℃; | General procedure: To a cooled solution of Boc-L-leucine (1.0 equiv.), the amine/alpha-aminoester HCl (1.2-1.5 equiv.), and PyBop 1.2 equiv. (or EDCI*HCl1.2 equiv. and HOBt 1.2 equiv.) in anhydrous DMF was added diisopropylethylamine (3.3-4.0 equiv.) gradually. The reaction mixture was stirred at room temperature for 5 h to overnight, diluted with ethyl acetate (50 mL for every 5 mL DMF), then extracted with 1 M HCl (3), saturated sodium bicarbonate (3), and brine (2). The organic layer was then dried with anhydrous sodium sulfate and the solvent was evaporated under vacuum to give the products which were purified by flash chromatography whenever needed. |
