Procedure

Cyclopropyl magnesium bromide (0.5 M solution in tetrahydrofuran, 6.3 mL, 3 equiv) was added to a solution of 4-(2-chloropyrimidin-5-yl)-N-(3-(4-cyclopropyl-4H-1,2,4-triazol-3-yl)phenyl)picolinamide (440 mg, 1.06 mmol) and Fe(acac)3 (37 mg, 10 mmol %) in N-methylpyridine (20 mL) and tetrahydrofuran (5 mL). After stirring for 5 minutes, the brown solution was quenched with 1 M hydrochloric acid (6 mL) and concentrated under reduced pressure at 70° C. The residue was purified by reverse-phase HPLC to give N-(3-(4-cyclopropyl-4H-1,2,4-triazol-3-yl)phenyl)-4-(2-cyclopropylpyrimidin-5-yl)picolinamide as a pale-yellow powder (200 mg, 45% yield).
