Reaction Steps

1,2-Bis(bromomethyl)-3,4-bis(trifluoromethyl)benzene (120 g., 0.3 mol.) in 450 ml. of ethanol is refluxed and treated with a solution of the sodium salt of p-methyl-benzene sulfonamide prepared by dissolving sodium (15.2 g., 0.66 mol.) in a mixture of p-methylbenzenesulfonamide (51.2 g., 0.3 mol.) in 650 ml. of methanol. The mixture is refluxed for two hours, cooled, neutralized with acetic acid and filtered to give 4,5-bis(trifluoromethyl)-2,3-di-hydro-1H-isoindole.
