실험 절차

500 mg of ethyl 8-anilino-4,5-dihydro-1H-pyrazolo[4,3-h]quinazoline-3-carboxylate (1.5 mmol) were dissolved in 10 mL of dry dimethylformamide and 1.63 mL of 1M lithium tert-butoxide in tetrahydrofuran were added to the cooled solution. After 30 minutes under stirring at 0° C. a solution of 432 mg of tert-butoxycarbonylaminopropyl bromide in 8 mL of dry tetrahydrofuran were added dropwise. After a night at room temperature the mixture was poured into a solution of NaH2PO4 and extracted with dichloromethane. The organic layer was then dried over Na2SO4 and the solvent evaporated, giving an oil that was treated according to the following step 7, without any further purification.
