Preparation of Sulindac: At first, 5-fluorine-2-methyl-3-oxo-2,3-dihydro-1H-indene can react with 2-nitrilylacetic acid to give a product(Ⅰ) through condensation reaction. Then the Sulindac can be prepared by reacting product(Ⅰ) with p-methylthiobenzaldehyde through condensation and oxidation reaction.

Uses of Sulindac: it may be used in the treatment of preterm labor. In addition, it can react with N-hydroxy-succinimide to get [6-fluoro-3-(4-methanesulfinyl-benzylidene)-2-methyl-3H-inden-1-yl]-acetic acid 2,5-dioxo-pyrrolidin-1-yl ester. This reaction will need reagent DCC and solvent tetrahydrofuran. The reaction time is 1 hour at reaction temperature of 0 °C. The yield is about 35%.
