Reaction Steps
To (2-Chloro-6-iodo-quinazolin-4-yl)-(5-cyclopropyl-2H-pyrazol-3-yl)-amine (208 mg, 0.606 mmol) in NMP (1 mL) was added 6-Amino-3-oxo-2,3-dihydro-indazole-1-carboxylic acid tert-butyl ester (252 mg, 1.01 mmol) and THF (3 mL) and the solution was heated to 100 C in a sealed tube. After 4 h, the solution was poured into sat. NaHCO3, and extracted with ethyl acetate, dried (Na2SO4) and concentrated in vacuum to give the title compound as a white solid (300 mg, 95% yield). LCMS m/e: 625.2 (M+H), 623.2 (M-H).
