Procedure

A solution of N-(5-chloro-7-ethynyl-1,3-benzodioxol-4-yl)-6-methoxy-7-(3-morpholin-4-ylpropoxy)quinazolin-4-amine (0.140 g, 0.28 mmol ), 5-iodo-1-[(4-methylphenyl)sulfonyl)-1H-pyrazole (0.147 g, 0.42 mmol) and diisopropylamine (0.078 ml, 0.56 mmol) in ethyl acetate (5 ml) was cooled to −20 C under a nitrogen atmosphere. To this mixture was added copper (I) iodide (0.016 g, 0.084 mmol) and bis(triphenylphospine)palladium (II) chloride (0.039 g, 0.056 mmol). The reaction mixture was allowed to warm to ambient temperature and then stirred overnight. The reaction mixture was filtered and then evaporated under reduced pressure. The residue was purified by flash chromatography on silica eluting with a mixture of 0-8% methanol in dichloromethane to give the product as a yellow solid (0.103 g, 51%). Mass Spectrum: M+H+ 717 and M+H− 715.
