Processes for preparing 5-fluoro-2-methyl-1-(4-methylthiobenzylidene)-3-indanacetonitrile and for preparing sulindac

The disclosure provides processes for preparing 5-fluoro-2-methyl-1-(4-methylthiobenzylidene)-3-indanacetonitrile and for preparing sulindac, relating to the field of medicine. The former comprises mixing 6-fluoro-2-methyl-1-indanone, cyanoacetic acid, a first organic solvent and an acetic acid-based catalyst to proceed with a first condensation reaction to give a first condensation reaction solution, which contains 5-fluoro-2-methyl-3-indanacetonitrile; and mixing the first condensation reaction solution, per se, with a base, a second organic solvent and 4-(methylthio)benzaldehyde to proceed with a second condensation reaction to give 5-fluoro-2-methyl-1-(4-methylthiobenzylidene)-3-indanacetonitrile. The process is a one-pot process without separation of 5-fluoro-2-methyl-3-indanacetonitrile from the solvent, shortening the synthetic route, simplifying the preparation process and improving the 5-fluoro-2-methyl-1-(4-methylthiobenzylidene)-3-indanacetonitrile yield.
