Reaction Steps

To a solution of the amino alcohol of Example 1e (720 mg, 2.72 mmol) in CH2Cl2 was added EDC (521 mg), HOBt (368 mg) and N-Boc-leucine (630 mg). The reaction was maintained at room temperature until complete consumption of the starting material was observed by TLC analysis. The reaction was diluted with ethyl acetate and washed with 1N HCl, sat. K2CO3, water, brine, dried (MgSO4), filtered and concentrated. Column chromatography of the residue (3% methanol:dichloromethane) gave 1.0 g of the title compound: MS(EI) 478 (M+H+).
