反応手順

To a solution of 1,3-diiodopropane (7.1 mL, 63 mmol) in tetrahydrofuran (50 mL) was added 3-(benzyloxy)pyridin-2(1H)-one (1.28 g, 6.3 mmol) and Na2CO3 (0.67 g, 6.3 mmol). The mixture was then stirred at 70° C. for 1 day. Reaction progress was monitored by ES-MS. After ESMS showed essentially complete consumption of the starting material 3-(benzyloxy)pyridin-2(1H)-one, the reaction was stopped. Then the reaction mixture was filtered, concentrated, and subjected to flash column chromatography (eluent: hexane:ethylacetate 1:1). Compound 7 was obtained (240 mg, 10% yield). Analysis: ES-MS (positive ion in MeOH/H2O): m/z=370.2, ([M+H]+, calculated: 370.03).
