Reaction Steps

Add 3-chloro-4-fluorobenzeneboronic acid (71 mg, 0.41 mmol) to a mixture of 3′-chloro-4-(1-methyl-1H-pyrazol-4-ylmethyl)-3,4,5,6-tetrahydro-2H-[1,2′]bipyrazinyl (104 mg, 0.34 mmol), potassium carbonate (113 mg, 0.82 mmol) and tetrakis(triphenyl-phosphine)palladium(0) (0.002 g, 0.002 mmol) in N,N-dimethylacetamide (2 mL) and water (1 mL). Purge with nitrogen and heat overnight at 110° C. Cool to room temperature, add water (10 mL), extract with DCM (3×20 mL), combine and purify using high pH reverse phase HPLC to give title compound (76 mg, 57.7%). MS (ES): m/z=387 [M+H]+.
