실험 절차

To a solution 8-[(2-bromophenyl)amino]-N-(2,6-diethylphenyl)-1-methyl-4,5-dihydro-1H-pyrazolo[4,3-h]quinazoline-3-carboxamide (68 mg, 0.129 mmol) in dioxane (0.5 mL) in a sealed tube, NaI (38 mg, 0.257 mmol), CuI (1.2 mg, 0.006 mmol), iodine (74 mg, 0.129 mmol) and trans-N,N′-dimethylcycloesane-1,2-diammine were added. The mixture was then heated at 150° C. for 12 h. Solvent evaporated to dryness and the crude solid was purified by flash chromatography on silica gel (eluant: dichloromethane/methanol: 8/2/) to 35 mg of the title compound (50% yield).
