実験手順
To a solution of N-(3-cyano-4,5-dihydrofuran-2-yl)-4-fluorobenzamide (5.0 g) obtained in Step E in N,N-dimethylformamide (30 mL) was added sodium iodide (6.5 g), and the mixture was stirred at 150° C. for 30 min. The solvent was evaporated under reduced pressure, and to the residue was added ice water. The resulting solid was collected by filtration, and washed with water. The residue was purified by silica gel column chromatography (hexane/ethyl acetate), and the resulting solid was washed with diisopropyl ether to give the title compound (1.3 g).
