Versuchsvorschrift
Dimethylamine (100 ml of 40% solution) was added to a solution of 5-(4-fluorobenzoyl)-4-methyl-2(3H)-thiazolone. (4.7 g) in ethanol (200 ml). The mixture as stirred in a sealed stainless steel vessel at 120° C. for 16 hours. After cooling to ambient temperature the solvent and excess dimethylamine was evaporated. The residue was recrystallized twice from ethanol to give the title compound mp. 224°-226° C.
