実験手順

1-Benzyl-4-piperazin-1-yl-phthalazine (500 mg, 1.64 mmol) and 2-chloro-5-nitropyridine are combined in a 10 mL microwave vial. Triethylamine (2.96 mL, 2.14 mmol) and NMP (4.8 mL) are added. The vial is sealed and heated to 180° C. for 15 min. The crude reaction mixture is poured into water and the resulting precipitate is isolated by filtration to afford the title compound (500 mg, 70% yield).
