To a stirred solution of 7.65 g (0.05 mol) of 2-nitrobenzyl alcohol in 75 ml of benzene containing 5.05 g (0.05 ml) of triethylamine was added 16.25 g (0.05 mol of hexadecanesulfonyl chloride. The mixture was stirred an additional four hours. The mixture was evaporated to dryness in vacuo and the solid taken up into a mixture of ether and water. The ether layer was separated and dried over MgSO4. Evaporation of the ether gave a solid which was crystallized from absolute ethanol (yield 14.3 g, m.p. 63°-65° C.).
