A mixture of 5-bromopyrimidin-2-one (2 mmol) and allylisocyanate (3 mmol) in dimethyl formamide (2 ml) was stirred together at room temperature until a clear solution resulted (ca. 3 h) before the solvent was distilled off at 1 mmHg, the residue triturated with ether and then with water; the residue was the title compound, yield 59%. MS (70 eV) m/e: 257/255 (M,O), 176 (31), 174 (33), 148 (9), 106 (8), 104 (8), 95 (60), 83 (20), 56 (100).
