Reaktionsschritte

To a solution of 1-benzyl-4-chloro-phthalazine (1.08 g, 4.04 mmol) in 8 mL NMP is added 4-(4-nitro-phenyl)piperidine (1 g, 4.85 mmol), TEA (1.68 mL, 12.12 mmol). The reaction mixture was heated to 150° C. for 45 min in a microwave reactor. Water was added to the reaction mixture to form a precipitate and the solid is collected by filtration and dried under vacuum. The resulting solid is purified by HPLC with acetonitril in water (from 20% to 100% with 3% 1-propanol) at 220 nm wavelength detection to provide the title compound (1.4 g, 78%).
