実験手順

Powdered sodium hydroxide (0.42 g) is added to a solution of N′-[5-((E)-3-dimethylamino-acryloyl)-4-methyl-thiazol-2-yl]-N,N-dimethyl-formamidine (0.93 g, prepared as described by S. Wang et al J. Med. Chem. 2004, 47, 1662-1675.) and 3,3,3-trifluoro-2,2-dimethyl-propionamidine hydrochloride (0.54 g) in 2-methoxyethanol (7 ml) and the mixture is heated at 125° C. for 1 hour with stirring. The reaction mixture is cooled, water is added, and the aqueous layer is extracted 4-times with 10% methanol in dichloromethane. The combined organic layers are purified by reversed phase chromatography and sodium bicarbonate is added to the fractions containing the title compound to give a white precipitate, which is collected by filtration. HPLC/MS: retention time 1.47 minutes, M+H 303.1.
