Reaction Steps

An ice-cold solution of 4-toluenesulfonyl chloride (6.4 g) and 4-ethylhex-2-yn-1,4-diol (McLamore, W. M. et al., J. Org. Chem., 19, 570-574 (1954) and Gouge, M., Ann. Chim., 6, 648-702 (1951)) (4.0 g) in ether (40 ml) was stirred with powdered potassium hydroxide (15 g) for 2 h. Water was added and the mixture was extracted with ether (2×250 ml). Work-up with chromatography using ether/pentane 1:1 (v/v) gave the title compound (6.5 g). 1H NMR: 0.91 (t, 6H), 1.55 (q, 4H), 1.83 (s, 1H), 2.45 (s, 2H), 4.76 (s, 2H), 7.36 (d, 2H), 7.82 (d, 2H).
