Reaction Steps

A microwave vial containing 3-acetyl-5-methyl-1-[3-(trifluoromethyl)phenyl]pyridazin-4(1H)-one (0.363 g, 1.2 mmol) and N,N-dimethylformamide dimethylacetal (2.5 mL) was heated at 120° C. for 20 min. The crude material was concentrated and purified by flash column chromatography (silica gel; methylene chloride to 1:9 methanol/methylene chloride) to provide 3-[3-(dimethylamino)prop-2-enoyl]-5-methyl-1-[3-(trifluoromethyl)phenyl]pyridazin-4(1H)-one (0.365 g, 87%) as an orange solid.
