2-[4-(Piperazin-1-yl)anilino]-4-(1-isopropyl-2-methyl-1H-imidazol-5-yl)pyrimidine (Example 20; 1.89 g, 5 mmol), di-isopropylethylamine (0.956 ml, 5.5 mmol) in DCM (25 ml) was treated at 0° C. with chloroacetyl chloride (0.438 ml, 5.5 mmol). The mixture was stirred at ambient for 2 hours, diluted with DCM (25 ml), washed with aqueous saturated sodium bicarbonate solution (20 ml) and aqueous saturated sodium chloride solution (20 ml). The solution was dried and evaporated at reduced pressure to give the title compound, (1.96 g, 87%). NMR (CDCl3) 8.30 (d, 1H), 7.44 (d, 2H), 7.35 (s, 1H), 6.96 (s, 1H), 6.92 (d, 1H), 6.85 (d, 1H), 5.68-5.56 (m, 1H), 4.12 (s, 2H), 3.83-3.76 (m, 2H), 3.72-3.67 (m, 2H), 3.22-3.11 (m, 4H), 2.59 (s, 3H), 1.48 (d, 6H); m/z 454.
