실험 절차
(E)-3-(4-chloro-phenyl)-N-[1-(2,2-diethoxy-ethyl)-2-oxo-1,2-dihydro-pyrimidin-4-yl]-acrylamide (c, 2.48 g, 6.8 mM) was dissolved in trifluoroacetic acid (37 mL) and stirred at room temperature for 4.5 hours. Trifluoroacetic acid was removed in vacuo, and toluene (40 mL) was added to remove the solvent in vacuo. The residual solid was added with ethyl acetate (15 mL) and 5% aqueous sodium bicarbonate (15 mL) and stirred at room temperature. The precipitated crystal was filtered to afford 2.28 g of the desired compound (E)-3-(4-chloro-phenyl)-N-[1-(2,2-dihydroxy-ethyl)-2-oxo-1,2-dihydro-pyrimidin-4-yl]-acrylamide (d) (yield 100%, colorless crystal).
