Reaction Steps

To a solution of 7-(ethylamino)-1-methyl-1,6-naphthyridin-2(1H)-one (20 mg, 0.1 mmol) and pyridine (27 μL, 0.3 mmol) in DCM (2 mL) was added phenylselenium bromide (72 mg, 0.3 mmol). The mixture was heated at 39° C. for 6 h, and then the solvent was removed under vacuum. The residue was chromatographed on silica gel (30% ethyl acetate in hexanes eluant) to provide the title compound. MS (m/z) 282.0 (M+1).
