Reaction Steps

4,5-Dimethyl-3-((R)-3-methyl-piperazin-1-yl)-6-pyridin-3-ylmethyl-pyridazine (350 mg, 1.18 mmol) and 5-chloro-pyrazine-2-carboxylic acid methyl ester (243.7 mg, 1.41 mmol) are added to a microwave vial followed by NMP (7 mL) and triethylamine (0.49 mL, 3.54 mmol). The vial is sealed and irradiated in the microwave at 145° C. for 30 min. The crude material is directly purified via flash chromatography on silica gel (0-20% methanol in CH2Cl2) to afford the title compound (30 mg, 6%).
