Reaction Steps

Methanesulphonyl chloride (0.055 ml, 0.711 mmole) was added to a solution of 4-(1,2-dimethylimidazol-5-yl)-2-(4-aminoanilino)pyrimidine (Example 165; 0.18 g, 0.64 mmole) and pyridine (0.052 ml, 0.64 mmole) in DCM (2.0 mL) cooled at 4° C. The mixture was allowed to warm to ambient temperature. The mixture was partitioned between saturated aqueous sodium hydrogen carbonate solution and EtOAc. The organic layer was separated, the volatiles evaporated and the residue purified by column chromatography on silica gel eluting with DCM/7M methanolic ammonia (96:4) to give the title compound (0.15 g, 65%) as a solid. NMR: 2.36 (s, 3H), 2.90 (s, 3H), 3.91 (s, 3H), 7.06 (d, 1H), 7.14 (d, 2H), 7.57 (s, 1H), 7.64 (d, 2H), 8.33 (d, 1H), 9.37 (br s, 1H), 9.42 (s, 1H); m/z 359.
