実験手順
Heat a solution of 2 chloro-5-iodo-1H-benzimidazole (3.0 g, 10.7 mmol) and spiro[isobenzofuran-1,4′-piperidin]-3-one (2.63 g, 12.9 mmol) in dry NMP (15 mL) at 100° C. for 14 hours. Pour the cooled mixture into water (50 mL) and extract twice with EtOAc (50 mL). Wash the combined extracts with brine (30 mL), dry, and evaporate in vacuo. Purify by flash column chromatography (50% EtOAc-hexane) to obtain 1′-(5-iodo-1H-benzimidazol-2-yl)-spiro[isobenzofuran-1,4′-piperidin]-3-one as a beige solid. C. 1′-(5-Pyridin-3-yl-1G-benzimidazol-2-yl)-spiro[isobenzofuran-1,44′-piperidin]-3-one
