Reaction Steps

CBz-L-valine (10 g, 40 mmol), 1,3-dihydroxybenzene (8.7 g, 79 mmol) N,N′dicychlohexylcarbodiimide (10.2 g, 44 mmol) and 4-dimethylaminopyridine (2.4 g, 20 mmol) were dissolved in DMF (50 ml) and left at ambient temperature overnight. The reaction mixture was filtered, the solvent removed under reduced pressure and the crude product was taken up in dichloromethane and filtered. Removal of the solvent followed by purification by chromatography (chloroform—methanol, 10:1) yielded pure title product (10.9 g, 79%).
