Reaction Steps

N-Methyl-6-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)quinazolin-2-amine (0.42 g, 1.5 mmol), 7-iodo-6-methylbenzo[d]isothiazol-3-amine (0.39 g, 1.3 mmol), dichlorobis(triphenyl-phosphine)palladium (II) (0.047 g, 0.067 mmol) and sodium carbonate (0.14 g, 1.3 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 50 to 100% EtOAc in hexanes. The clean fractions were triturated with warm ether and the solid collected by suction filtration and dried to give 6-(3-amino-6-methylbenzo[d]isothiazol-7-yl)-N-methylquinazolin-2-amine as a tan solid. MS(M+H)+ 322.
