Versuchsvorschrift

To an ice-cold solution of 2,6-dimethyl piperazine (179 mmol, 20.4 g), methylene chloride (200 mL), and triethylamine (214 mmol, 29.9 mL) was added dropwise dimethylcarbamoyl chloride (179 mmol, 16.4 mL). After 4 hr the reaction was quenched with a saturated sodium bicarbonate solution and the methylene chloride layer was collected, dried, filtered and the filtrate was evaporated to dryness to obtain an orange oil, 2,6-dimethyl-piperazine-1-carboxylic acid dimethylamide (70%, 23.1 g).
