Reaction Steps

1 mmol of 2-[2-(2,4-dichlorophenyl)-2-oxoethyl]isoindoline-1,3-dione was heated to 80° C. in neat N,N-dimethylformamidedimethyl acetal for six hours. The reaction mixture is concentrated in vacuo and purified by trituration with diethyl ether to obtain 2-{2-(2,4-dichlorophenyl)-1-[(dimethylamino)methylene]-2-oxoethyl}-isoindoline-1,3-dione.
