Versuchsvorschrift

To a solution of 3.85 g. of 2-decyn-1-ol and 3.95 g. of pyridine in 100 ml. ether is added 3.0 g. of cyclopropanecarboxylic acid chloride. The mixture is stirred overnight under nitrogen. The reaction mixture is poured into distilled water, washed with dilute hydrochloric acid and then with sodium bicarbonate and solvent removed to yield 2-decynyl cyclopropanecarboxylate, b.p. 96°-97° (bath) at 0.1 mm.
