Procedure

[6-(3-Amino-prop-1-ynyl)-quinazolin-4-yl]-[1-(3-fluoro-benzyl)-1H-indazol-5-yl]-amine (280 mg, 0.663 mmol) is treated with diphenyl cyanocarbonimidate (163 mg, 1.031 equiv.) in a mixture of i-PrOH (12 ml) and THF (4 ml). Stir mixture overnight, then concentrate to dryness and chromatograph on silica (EtOAc/hexanes) to obtain 186.3 mg (49.6%) of pure desired product.
