Procedure

A mixture of .06 mole of sodium 5-cyano-2-methyl-1-(p-methylsulfinylbenzylidene)-3-indenylacetate and 0.05 mole of trityl bromide in 100 ml. anhydrous benzene is refluxed with rapid stirring under nitrogen for 5 hours. The hot reaction mixture is filtered and the filtrate is concentrated in vacuo. The residue is recrystallized from methyl ethyl ketone to give trityl 5-cyano-2-methyl-1-(p-methylsulfinylbenzylidene)-3-indenylacetate.
