Reaction Conditions

Reaction Steps

n-Octyl alcohol (300 g) was saturated with hydrogen chloride gas passed in subsurface during about 2 hr. while the temperature rose to 55° C. Benzotriazolecarboxylic acid (16.3 g) prepared by the method of Example 1 was added and the reaction mixture was refluxed at 110° C. under reduced pressure for 1.25 hr. during which water was azeotropically distilled and collected in a Dean-Stark trap. Unreacted octyl alcohol was removed by reduced pressure distillation. The residue, which was solid when cooled, was recrystallized from benzene and washed with n-pentane to afford the ester, n-octyl benzotriazolecarboxylate, as a solid mp 64°-65° C. The infrared spectrum was similar to that of the ethyl ester, consistent with the ester structure, and the elemental analysis was as follows:
