Reaction Steps
11.4 g of N-[(R)-1-[(1,1-dimethylethoxy)carbonyl]-3-[[(1,1-dimethylethyl)dimethylsilyl]oxy]propyl]-L-leucine, prepared as in Example I, 3.64 g benzylamine, and 4.59 g hydroxybenzotriazole in 150 mL DMF was sparged with nitrogen for 10 min. 7.02 g of d icyclohexylcarbodiimide in 50 mL DMF was added dropwise at 0° C. The mixture was stirred for 15 h at 23° C., filtered, and the solvents were removed by evaporation. The residue was purified by silica chromatography using 80% hexane-ethyl acetate as eluent to give the title compound as a brown oil; 8.8 g.
