Procedure
Bromine (0.004 mol) was added to an aqueous solution (20 ml) of 4-methylpyrimid-2-one (0.002 mol). The reaction mixture was left at room temperature for 4 h before evaporation. The residue was triturated with acetone and recrystallised from acetic acid; yield 80%, m.p. (Found: C, 22.2; H, 2.3; Br, 59.2. Calc. for C5H5N2OBr. HBr: C, 22.2; H, 2.22; Br, 59.25).
