By the same procedure as in Example 1, 1.22 g (10.0 millimoles) of 4-methylocta-4-ene-1,7-diyne-3-ol, 2.66 g (10.0 millimoles) of α-isopropyl-3,4-dichlorophenylacetyl chloride and 1.58 g (20.0 millimoles) of pyridine are reacted, followed by purification on silica gel column. Thus, 3.18 g of the objective ester is obtained as a pale yellow oily substance (87.5% of theoretical yield). nD24.0 1.5314
