Versuchsvorschrift

Hitherto this compound has been prepared by reacting o-chloroacetophenone with the sodium or potassium salt of 2,4-dichlorophenol at a temperature of at least 120° C. in the presence of a copper catalyst to produce 2-(2,4-dichlorophenoxy)acetophenone. This is then reacted with sulphur and morpholine to afford a thioacetmorpholide which is thereafter hydrolysed.
