Reaction Conditions

Reaction Steps

A 50% aqueous dimethylamine solution (1.0 ml, 11 mmol) was added to a solution of trans-isomer (128 mg, 0.35 mmol) of 3-(2-chloroethyl)-5-(n-nonyl)-2-(3-pyridyl)thiazolidin-4-one in dimethylsulfoxide (3 ml). The mixture, placed in a sealed tube, was heated at 100° C. for 2 hours. After removal of the solvent by evaporation under reduced pressure, the residue was dissolved in chloroform (30 ml). The solution was washed twice with saturated aqueous NaHCO3 and dried. Removal of the chloroform gave the intended trans-isomer (131 mg, 100% of theoretical) of 3-(2-dimethylaminoethyl)-5-(n-nonyl)-2-(3-pyridyl)thiazolidin-4-one in oily form.
