Versuchsvorschrift
To a solution of 1,2,3-thiadiazole-5-carbonyl chloride (10.00 g, 61.5 mmol) and N,O-dimethylhydroxylamine hydrochloride (7.20 g, 73.8 mmol) in dichloromethane (200 ml) was added triethylamine (20.6 ml, 147.6 mmol) at 0° C. After stirring for 2 h at room temperature, the mixture was diluted with dichloromethane (300 ml), washed with water (200 ml×2) and dried (MgSO4). Removal of solvent gave 11.31 g (98%) of the title compound as brown crystals.
