Triethylamine → HCID 19682531, compound

Participants

Reaction Steps

3.8 g of N-aminomorpholine (36.9 mmol) and 5.1 ml of triethylamine (3.7 g, 36.9 mmol) were dissolved at room temperature in 40 ml of methylene chloride. Again at room temperature 4.8 ml of n-butanesulfonyl chloride (5.8 g, 36.9 mmol) were added dropwise to this solution over the course of one hour. After 20 h of stirring at room temperature the reaction mixture was extracted by shaking twice with 50 ml of water and the organic phase was dried over magnesium sulphate and concentrated. The 6.7 g of crude product obtained were recrystallized from 30 ml of tert-butyl methyl ether. The constitution of the target compound was verified by NMR spectroscopy.
