To a solution of 2-(5-acetamido-6-oxo-2-phenyl-1,6-dihydro-1-pyrimidinyl)-N-(2-tert-butyldimethylsilyloxy-3,3,3-trifluoro-1-isopropylpropyl)acetamide (0.86 g) in tetrahydrofuran (15 mL) at 0° C. was added tetrabutylammonium fluoride (1.95 mL, 1M in tetrahydrofuran) and the resulting solution was allowed to stir for 5 min. The mixture was poured into saturated aqueous ammonium chloride and the product extracted into ethyl acetate. The organic solution was washed (water), dried, and evaporated. The resulting white solid was collected and washed with ether:hexane to provide 2-(5-acetamido-6-oxo-2-phenyl-1,6-dihydro-1-pyrimidinyl)-N-(3,3,3-trifluoro-1-isopropyl-2-hydroxypropyl)acetamide (0.6 g); NMR: 8.87 (s,1), 8.07 (d,1), 7.57 (m,5), 4.62 (d,1), 4.42 (d,1), 4.10 (m,1), 3.68 (t,1), 2.18 (s,3), 1.80 (m,1), 0.89 (d,3), 0.82 (d,3).
