Versuchsvorschrift
To 3.5 (15.4 mmol) of 4-(isopropylamino)-2-(methylthio)pyrimidine-5-carboxylic acid is added 9.0 mL (123.2 mmol) of thionyl chloride, and the reaction mixture is heated at 50° C. for 1 hour, cooled to room temperature, and concentrated. The residue is twice suspended in anhydrous toluene and concentrated to give a colorless solid, 4-(isopropylamino)-2-(methylthio) pyrimidine-5-carboxylic acid chloride.
