Reaction Steps

10 g of p-toluamide were suspended in 100 ml of ether and 12.5 ml of pyridine under argon. The 5.8 ml of thionyl chloride dissolved in 10 ml of ether were added dropwise at 5° C. and the mixture was stirred for a further 5 minutes. Subsequently, the cooling was removed and the mixture was stirred at room temperature for a further 16 hours.
