Procedure

5-Iodo-6-methyl-1-(3-(trifluoromethyl)phenoxy)isoquinoline (0.170 g, 0.396 mmol), N-methyl-6-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)quinazolin-2-amine (0.124 g, 0.436 mmol), dichlorobis(triphenyl-phosphine)palladium (II) (0.0139 g, 0.0198 mmol), and sodium carbonate (0.0840 g, 0.792 mmol) were all placed in a clear microwave vial along with 5 ml of 9:1 DMF:water. The vial was capped and heated in a Personal Chemistry SmithSynthesizer to 150° C. for 10 minutes. The reaction was diluted with water and extracted with EtAOc. The organic layer was washed (2×) with an aqueous saturated solution of sodium bicarbonate, then with water and then brine. The organic layer was then dried with sodium sulfate and purified by column chromatography on silica gel using a gradient of 30-70% EtOAc in hexanes. The clean fractions were reduced in vacuo and the residue triturated with ether to give N-methyl-6-(6-methyl-1-(3-(trifluoromethyl)phenoxy)isoquinolin-5-yl)quinazolin-2-amine as a light yellow solid. MS (M+H)+ 461.
