A solution of 2-(2-(2,5-dichlorophenyl)-2-oxoethyl)isoindoline-1,3-dione (0.10 g, 0.30 mmol) in 1,1-dimethoxy-N,N-dimethylmethanamine (8 mL) was heated at reflux for 2 hours. The resultant mixture was then concentrated. Purification by flash column chromatography afforded 2-(3-(2,5-dichlorophenyl)-1-(dimethylamino)-3-oxoprop-1-en-2-yl)isoindoline-1,3-dione as a solid (0.90 g, 77% yield).
