Procedure

Dimethylamine (2.0 M) in THF (1.5 ml) was added to a stirred suspension of 2-{4-[4-(vinylsulphonyl)piperazin-1-yl]anilino}-4-(1-isopropyl-2-methyl-1H-imidazol-5-yl)pyrimidine (Example 29; 140 mg 0.3 mmol) in THF (3 ml) at room temperature. Additional dimethylamine solution (0.5 ml) was added after 2 hours. The reaction was stirred for 1 hour then stood overnight. The reaction was evaporated under reduced pressure, triturated with ether and filtered to give the title compound as a yellow solid. (134 mg 89%). NMR: 1.40 (d, 6H), 2.46 (s, 3H), 2.62 (t, 2H), 3.13 (t, 4H), 3.20-3.35 (2H and 4H)[under exchangeables], 5.68 (septuplet, 1H), 6.92 (d, 2H), 6.95 (d, 1H), 7.38 (s, 1H), 7.47 (d, 2H), 8.31 (d, 1H), 9.18 (s, 1H) [+duetero acetic acid: 3.01 (b d, 2H), 3.14 (t, 4H), 3.33 (t, 4H), 3.37 (m, 2H)]; m/z 478.
