Versuchsvorschrift
A 100 mL round bottom flask was charged with the 1-[6-(3-cyanophenyl)imidazo [2,1-b][1,3]thiazol-5-yl]ethanone (4.30 g, 16.1 mmol) and dimethylformamide dimethylacetal (40 mL). The mixture was refluxed for 6 hours and then concentrated in vacuo to provide a dark solid. LCMS: 323 [M+H]; purity: 90% by UV at 254 nm. This crude was used for next step reaction without further purification.
