12-Chloro-dodec-5-yne (1 mmol) was mixed with potassium iodide (3 mmol) and 2-picoline (3 mmol) in butanone. room temperature. The butanone was removed in a vacuum, and the resulting residue was partitioned between water and ethyl ether. The aqueous layer was washed extensively with ether until no 2-picoline was left in the aqueous layer. The resulting aqueous solution of the product was extracted with chloroform. The chloroform was removed to afford the product (85%). 1HNMR (300 MHz, CDCl3, ppm) 9.62 (d, 1H), 8.39 (dd, 1H), 7.99 (m, 1H), 7.91 (d, 1H), 4.88 (t, 2H), 2.97 (s, 3H), 2.12-2.20 m, 4H), 1.90-2.00 (m, 2H), 1.32-1.58 (m, 8H), 0.88 (t, 3H).
