実験手順

Powdered sodium hydroxide (150 mg) is added to a solution of N′-[5-(3-dimethylamino-acryloyl)-4-methyl-thiazol-2-yl]-N,N-dimethyl-formamidine (0.5 g, prepared as described by S. Wang et al J. Med. Chem. 2004, 47, 1662-1675.) and 1,1-diethylguanidine (259 mg) in 2-methoxyethanol (1.9 ml) and the mixture heated at 125° C. for 1 hour with stirring. The reaction mixture is concentrated under vacuum and purified by normal phase chromatography, eluent; DCM/EtOAc, to give the title compound. ESI-MS: M+H 264 and M−H 262.
