Procedure

Methanesulphonyl chloride (3.5 g.) was added slowly to 4-(2-aminoethyl)pyridine (3.6 g.) and triethylamine (3.0 g.) in chloroform (40 ml.). The temperature was maintained below 40° C. during the addition, after which the orange solution was left to stand at room temperature overnight. Water (50 ml.) was then added, the chloroform phase was separated, and the aqueous phase extracted with chloroform (100 ml.). The two chloroform solutions were combined, dried (MgSO4) and taken to dryness in vacuo to give a yellow oil which solidified immediately. This solid was crystallized from ethanol to yield white crystals of 4-(2-methanesulphonamido-ethyl)pyridine (1.4 g.).
