Reaction Steps

800 mg of tetrabutylammonium di-tert-butylphosphate are added to 270 mg of [2-amino-6-(2-chloromethyl-4,5-difluorophenyl)quinazolin-4-yl]-(1,3-dihydroisoindol-2-yl)methanone dissolved in 20 ml of acetonitrile, and the solution obtained is heated at 80° C. for 2 h. After cooling to 25° C., undissolved material is filtered off, and the filtrate is evaporated to dryness in vacuo. The residue is dissolved in 1 ml of dimethyl sulfoxide and purified by chromatography (reversed phase).
