Reaction Conditions

Reaction Steps

A mixture of 7-hydroxy-6-methoxy-4-[2-methyl-5-(2-morpholinopyridine-4-carboxamido)anilino]quinazoline (250 mg), 3-methylsulphonylpropyl 4-toluenesulphonate (150 mg), cesium carbonate (501 mg) and N,N-dimethylacetamide (5 ml) was stirred and heated to 100° C. for 1 hour. After cooling the reaction mixture to ambient temperature, water was added and the precipitated solid was isolated and dried under vacuum. The material so obtained was purified by column chromatography on silica using a 10:1 mixture of methylene chloride and methanol as eluent. There was thus obtained the title compound as a solid (38 mg); NMR: 2.14 (s, 3H), 2.13 (m, 2H), 3.02 (s, 3H), 3.24 (m, 2H), 3.49 (m, 4H), 3.68 (m, 4H), 3.93 (s, 3H), 4.29 (t, 2H), 7.08 (d, 1H), 7.16 (s, 1H), 7.21 (s, 1H), 7.27 (d, 1H), 7.58 (d, 1H), 7.76 (s, 1H), 7.83 (s, 1H), 8.25 (d, 1H), 8.27 (s, 1H), 9.4 (s, 1H), 10.28 (s, 1H); m/s: M+H+ 607.
