2-[4-(2,2-Dimethylaziridin-1-ylsulphonyl)anilino]-4-(1,2-dimethylimidazol-5-yl)pyrimidine (Example 47; 200 mg, 0.502 mmol) was dissolved on warming in morpholine (4.7 ml, excess) and stirred at room temperature for 3 days. The excess morpholine was removed in vacuo and the residue dissolved in EtOAc (40 ml) and washed with water (3×40 ml), dried the solvent evaporated in vacuo. The crude product was triturated with ether filtered washed with ether and air-dried to give the title compound (200 mg, 82%) as a white solid. NMR 1.03 (s, 6H), 2.27 (s, 2H), 2.38 (s, 3H), 2.47 (m, 4H), 3.52 (m, 4H), 3.95 (s, 3H), 7.05 (s, 1H), 7.2 (d, 1H), 7.63 (s, 1H), 7.72 (d, 2H), 7.88 (d, 2H), 8.43 (d, 1H), 9.86 (s, 1H); m/z 486.
