To methyl 4-(3-amino-6-bromopyrazin-2-yl)-2-fluorobenzoate (For Synthesis see Example 34, Step 2) (100 mg, 0.307 mmol) in DME (3 mL) and 2 M sodium carbonate (0.75 mL, 1.5 mmol) was added tert-butyl 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole-1-carboxylate (90 mg, 0.307 mmol) followed by PdCl2(dppf)-CH2Cl2 adduct (25.04 mg, 0.031 mmol). The reaction mixture was heated in microwave at 120° C. for 15 min. The reaction mixture was partitioned between ethyl acetate and water. The organic layer was separated, washed with water and brine, dried over sodium sulfate, filtered and evaporated. The residue was proceeded to next step without purification (90 mg, 74%, 80% purity). LCMS (m/z): 314.1 (MH+), 0.595 min.
