1.66 g (6.77 mmol) of N-(5-acetyl-2-fluoro-phenyl)-N-methyl-methanesulfonamide were dissolved in 3.35 ml (3.0 g) (25.18 mmol) of N,N-dimethylformamide dimethylacetal and the resultant solution was refluxed for 2.5 hours. The mixture was cooled at room temperature. To the solid formed was added 20 ml of n-hexane and filtered to yield a solid which was crystallized from ethyl acetate. 1.37 g of N-[5-(3-dimethylamino-acryloyl)-2-fluoro-phenyl]-N-methyl-methanesulfonamide as a yellowish-white solid were obtained (yield 67.4%).
