実験手順
10% Aqueous sodium hydroxide solution (48 ml) was added to a mixture of ethyl 2-(4-cyanobenzoylimino)-3,4-dimethylthiazoline-5-carboxylate (9.88 g), methylene chloride (250 ml) and methanol (250 ml), followed by stirring at room temperature for 17 hours. The reaction mixture was concentrated under reduced pressure, and the precipitated crystals were collected by filtration to give sodium 2-(4-cyanobenzoylimino)-3,4-dimethylthiazoline-5-carboxylate (10.0 g).
