90 °C

To a solution of (4-methoxy-dibenzofuran-1-yl)-acetonitrile (7 g, 0.029 mol) in acetonitrile (200 ml), Triton B (2.7 ml, 0.0147 mol) was added under N2 at RT. The reaction mass was heated to reflux and at reflux temperature methyl acrylate (28.25 ml, 0.295 mol) was added drop wise. The reaction mass was stirred for 4 hrs at 90° C. Once the product is formed, the reaction mass was diluted with ethyl acetate and concentrated under vacuum. 4-cyano-4-(4-methoxy-dibenzofuran-1-yl)-heptane dioic acid dimethyl ester was isolated by column chromatography. Yield 8 g (65%)
