Reaction Steps

(R)-2-Methyl-3,4,5,6-tetrahydro-2H-[1,2′]bipyrazinyl-5′-carboxylic acid methyl ester (150 mg, 0.63 mmol), 1-benzyl-4-chloro-phthalazine (161.75 mg, 0.635 mmol) are added into a microwave vial followed by NMP (3.3 mL) and triethylamine (0.265 mL, 1.91 mmol). The vial is sealed and irradiated in the microwave at 180° C. for 30 min. The crude material is directly purified via flash chromatography on silica gel (40-100% EtOAc in heptane). Desired product is then washed with water and lyophilized to afford the title compound (52 mg, 18% yield).
