Reaction Steps
(6-Chloro-4,5-dimethyl-pyridazin-3-yl)-pyridin-2-yl-methanone (550 mg, 2.22 mmol), (R)-2-methyl-piperazine (320 mg, 3.20 mmol) are added into a microwave vial followed by NMP (6 mL) and triethylamine (0.92 mL, 6.66 mmol). The vial is sealed and irradiated in the microwave at 180° C. for 1 h. The crude material is directly purified via flash chromatography on silica gel (20-70% methanol in CH2Cl2) to afford the title compound (671 mg, 97%).
