Reaction Steps

4-[(1-Methyl-1H-pyrazol-3-yl)amino]quinazolin-6-ol (250 mg; 1.033 mmol) and 424 mg (2.219 mmol) of the above-prepared sulfone compound were added to a solution of 320 mg (2.857 mmol) of tert-butoxy potassium in 24 ml of N,N-dimethylacetamide and the mixture was stirred at 77° C. for 12 hours. To the reaction solution was added water followed by extracting with chloroform. The organic layer was dried and concentrated and the resulting residue was purified by a reversed phase preparative HPLC (0.1% TFA-containing water:acetonitrile=90:10→10:90) to give 120 mg (yield: 28%) of the title compound as a yellow solid.
