Reaction Steps

15.29 g (61 mmol) of Z-Val-OH and 21.96 g (61 mmol) of H-Val-MeVal-Pro-OMe were dissolved in 610 ml of dichloromethane and cooled to 0° C. After addition of 8.16 mol(73.2 mmol) of N-methylmorpholine, 2.77 g (20.3 mmol) of HOBt and 11.74 g (61 mmol) of EDCI, the reaction mixture was stirred overnight at room temperature, diluted with dichloromethane and thoroughly washed with saturated aqueous NaHCO3 solution (3×), water (1×), 5% citric acid (3×) and saturated NaCl solution. The organic phase was dried over sodium sulfate, filtered and evaporated to dryness to yield 31.96 g of the product.
