실험 절차
2,3-Dihydro-1-methyl-3-(phenylmethyl)-2-thioxo-6-(trifluoromethyl)-4(1H)-pyrimidinone (1.0 g) was dissolved in m-xylene (15 ml) and anhydrous aluminum chloride (0.58 g) was added. The solution was refluxed for 4 hr and poured onto ice water. Extraction with ethyl acetate and evaporation of the solvent in vacuo afforded a residue which was triturated with diethyl ether to afford the title compound (0.34 g). 1H NMR, CDCl3, 3.86 (3H, m), 6.49 (1H, s), 10.62 (1H, br s).
