Successive conversion of N-bis (2-hydroxyethyl)-p-toluenesulphonamide (I b) to respective dimethanesulphonate and difluoro derivatives (II a, III a, and III c) was found to provide a convenient route to N-bis (2-fluoroethyl) amine. Reaction of N-bis (2-methanesulphonyl- oxyethyl)-p-toluenesulphonamide (III a) with limited quantities of potassium fluoride, in several pro tic solvents, was shown to yield N-(p-toluenesulphonyl) morpholine (IV).
