Morpholine → 4-(4-Bromo-2-trifluoromethyl-benzenesulfonyl)-morpholine

Participants

Reaction Steps

A solution of 4-bromo-2-trifluoromethyl-benzenesulfonyl chloride (5.00 g, 15.46 mmol) in THF (5 ml) was added to a solution of morpholine (1.62 ml, 18.55 mmol) and triethylamine (2.15 ml, 15.46 mmol) in tetrahydrofurane. The reaction mixture was stirred for 12 h at RT. Ethyl acetate (80 ml) was added, the organic phase was separated and washed with water (20 ml), hydrochloric acid (1 M, 20 ml) and brine (20 ml) and dried over sodium sulphate. After evaporation the product was obtained (5.708 g, 99%) and used in the next step without further purification.
