Procedure

3.1 g (7 mmol) of N-(2-benzyloxy-4-fluoro-phenyl)-7-bromo-5-methyl-quinazolin-4-amine, 0.8 g (8.8 mmol) dimethylsulphoximine (IV.1), 0.4 g (1.4 mmol) 2-(di-t-butylphosphino) biphenyl, 0.5 g (0.5 mmol) Pd2dba3 and 1.0 g (10.2 mmol) sodium tert-butoxide in dioxane are heated to 80° C. for 4.5 h. After cooling to RT the reaction mixture is filtered, diluted with water and extracted with EtOAc. The organic layers are pooled, dried and evaporated. The residue is purified by FC giving rise to N-(2-benzyloxy-4-fluoro-phenyl)-7-[[dimethyl(oxo)-λ6-sulfanylidene]amino]-5-methyl-quinazolin-4-amine.
