Procedure

Dissolved methyl 4-{[(3S)-1-(tert-butoxycarbonyl)piperidin-3-yl]amino}-6-iodoquinazoline-8-carboxylate (380.00 mg; 0.74 mmol; 1.00 eq.) in iPrOH (2.00 ml) and DMSO (2.00 ml) and then added ammonium hydroxide (5.00 ml). Stirred mixture at room temperature for 2.5 days. LCMS: M+1=498 major peak. Partially concentrated reaction. Diluted with water and filtered the resulting solids. Washed with water and dried to give an off-white solid (110 mg). LCMS: M+1=498.
