Participants

Reaction Steps

(6-Chloro-4,5-dimethyl-pyridazin-3-yl)-pyridin-3-yl-methanone (1.2 g, 4.84 mmol) and (R)-2-methy 1-piperazine (485 mg, 4.84 mmol) are added to a microwave vial followed by NMP (17 mL) and triethylamine (2.01 mL, 14.49 mmol). The vial is sealed and irradiated in the microwave at 170° C. for 30 min. The crude material is directly purified via flash chromatography on silica gel (0-20% methanol in CH2Cl2). The resulting oil is co-evaporated with CH2Cl2 and heptane to afford the title compound as a powder (1350 mg, 90%).
