Versuchsvorschrift

A mixture of 4-cyanobenzoyl chloride (166.5 g), ethyl 2-amino-4-methylthiazole-5-carboxylate hydrochloride (224.0 g) and pyridine (2000 ml) was stirred at room temperature for 70 minutes. The precipitated crystals were collected by filtration, and washed with 3% hydrochloric acid and water to give ethyl 2-(4-cyanobenzoylamino)-4-methylthiazole-5-carboxylate (262.0 g).
