実験手順

2-thiobarbituric acid (14.4 g) was suspended in pyridine and 4-fluorophenyl isocyanate (13.7 g) was added thereto. The reaction mixture was maintained at 90° C. for one hour, and thereafter left overnight at room temperature. The solids formed were collected, washed with pyridine, re-suspended in ethanol, and again collected and dried. A pale pink powder product was thereby obtained, mp >250° C. (dec.), NMR (DMSO) 7.0-7.7δ (multiplet, integral 4); 10.7-11.4δ (overlapping broad singlets, combined integral 4). MS, M/e 281 (Calc., 281).
