Through the use of o-toluenesulfonyl chloride and pyridine it has been found possible to form 2-oxazolines from acylaminonlkanols in which the amido group is attached to primary, secondary or tertiary carbon, and the alcohol is primary or secondary. The yield of oxazoline ranged from 21-85y0 depending upon the structure of the ncylaminoalkanol. Sulfonic acid esters are suggested as intermediates.
