50% | With dmap; dicyclohexyl-carbodiimide; In dichloromethane; at 0 - 20℃; for 48h; | Dodecanedioic acid benzyl ester 2-(11-benzyloxycarbonyl-undecanoyloxy)-3-dimethylamino-propyl ester (29a) To an ice-cold solution of 24a (1.78 g, 5.5 mmol), 3-dimethylamino-propane-1,2-diol (0.3 mL, 2.5 mmol) and DMAP (catalytic amount) in DCM (15 mL) was slowly added a solution of DCC (1.1 g, 5.5 mmol) in DCM (5 mL). After the addition, the solution was warmed to room temperature and stirred for 2 days. The reaction mixture was then filtered to remove the insoluble DCU. Concentration of the filtrate followed by chromatography (50percent EtOAc/DCM to 100percent EtOAC) afforded 0.9 g (50percent yield) product as colorless oil. The characterization data were consistent with the proposed structure. |
