実験手順
To a solution of 5-cyano-5-(4-methoxy-dibenzofuran-1-yl)-2-oxo-cyclohexane carboxylic acid methyl ester obtained in example 1 (7 g, 0.0185 mol) in DMSO (140 ml) and water (9 ml) was added sodium chloride (7 g, 0.119 mol) at room temperature. The reaction mass was heated to 130-140° C. for 5 hrs. Once the product is formed, the reaction mass was quenched with water and extracted with ethyl acetate. The organic layer was dried with sodium sulfate and concentrated under vacuum. 1-(4-methoxy-dibenzofuran-1-yl)-4-oxo-cyclohexane carbonitrile was isolated by column chromatography. Yield 4.2 g (71%)
