To 1-(2,3-dihydrobenzofuran-5-yl)-N-(2′-methoxy-3-methyl-2,4′-bipyridin-6-yl)cyclopropanecarboxamide (42 mg, 0.1 mmol) in chloroform (2 mL) was added iodotrimethylsilane (63 mg, 0.3 mmol). The reaction mixture was heated to 60° C. for one hour. The reaction was evaporated to dryness and the residue was dissolved in N,N-dimethylformamide (1 mL) and purified by reverse-phase preparative liquid chromatography. The resulting trifluoroacetic acid salt was dissolved in dichloromethane (5 mL) and washed with a saturated sodium bicarbonate solution (5 mL). The organics were dried over sodium sulfate and evaporated to dryness to yield the product (14 mg, 36%) ESI-MS m/z calc. 387.43. found 388.5 (M+1)+.
