Procedure

To a solution of 2-[5-benzyloxycarbonylamino-6-oxo-2-(2-thienyl)-1,6-dihydro-1-pyrimidinyl]-N-(3,3,3-trifluoro-2-hydroxy-1-isopropylpropyl)acetamide (1.95 g), triethylamine (1.4 mL), and 4-dimethylaminopyridine (10 mg) in dichloromethane (35 mL) was added pivaloyl chloride (0.53 mL); and the resulting solution allowed to stir for 2 h. The solution was diluted with ethyl acetate, washed (saturated aqueous sodium bicarbonate (twice), saturated aqueous ammonium chloride, and brine), dried, and evaporated. Purification by chromatography, eluting with ethyl acetate:dichloromethane (10:90), afforded the ester (1.80 g) as a white foam; TLC: Rf =0.34, ethyl acetate:dichloromethane (10:90); MS: m/z=623(M+1).
