Reaction Steps

To a solution of chloromethyl 5-(N-CBz-L-valyloxy)-2,2-dimethylvalerate (3.85 g, 9 mmol) in acetonitrile (50 mL), was added sodium iodide (5.40 g, 36 mmol). The solution was stirred for 4 h at 60° C. The resulting suspension was filtered and the filtrate was evaporated. The residue was dissolved in CH2Cl2 and washed with aqueous sodium thiosulfate (0.1 M). The organic phase was dried (Na2SO4) and concentrated under reduced pressure. The crude product was column chromatographed (silica gel, 1% MeOH in CH2Cl2), to give 4.26 g of iodomethyl 5(N-CBz-L-valyloxy)-2,2-dimethylvalerate
