실험 절차
1 g (7.5 mmol) 2,4-Dichloro-9-fluoro-3-phenylpyrimido[1,2-b]indazole (intermediate example Int-1-0, step 2) and 430 mg (8.4 mmol) cyclopropylamine were dissolved in 8.4 mL DMF and heated in the microwave for 20′ at 100° C. The solvent was evaporated and the residue was purified by chromatography on silicagel (eluents: dichloromethane/methanol) to yield 560 mg (52.7%) of the desired compound.
