Reaktionsschritte

130 g (1.7 moles) of thioacetic acid, 50 g (0.3 mole) of methyl 4-cyanobenzoate and 12 ml of glacial acetic acid were stirred for 2 hours at 80° C. The mixture was allowed to cool, 200 ml of 1:1 isopropanol/water was added, the mixture was stirred for a short time and the crystals formed were filtered off under suction. 45.5 g of 4-carbomethoxybenzothiamide of melting point 188°-190° C. were obtained in this manner.
