Procedure:
A solution of 530 mg 5-(4-chloro-phenyl)-2,2-dimethyl-5-prop-2-ynyl-(1,3)dioxolan-4-one in 10 ml tetrahydrofurane and 5 ml methanol is treated with 2 ml of 1N NaOH and heated at 60° C. for 1 hour. Then the solution is cooled down, diluted with water and washed with ether. Then the aqueous solution is acidified with 1N HCl and extracted with ethyl acetate. The extracts are dried over sodium sulfate and evaporated to obtain the 2-(4-chlorophenyl)-2-hydroxy-pent-4-ynoic acid of a brownish thick oil which is used for the next step.

Procedure:
In 10 ml of methylene chloride is dissolved 1.00 g of 3-(acetyloxy)-4-isobutoxybenzoic acid. After adding 0.41 ml of oxalyl chloride and 20 μl of N,N-dimethylformamide successively at ambient temperature, the mixture thus obtained is stirred at ambient temperature for one hour. Then, 1.06 g of aluminum chloride and 1.15 g of 1,3-diisobutoxybenzene are successively added at 5-10° C., and the mixture is stirred at the same temperature as above for one hour. The reaction mixture is added to a mixture of methylene chloride and ice water, and the organic layer is separated. The organic layer is successively washed with water and saturated aqueous solution of sodium chloride and dried over anhydrous magnesium sulfate, and the solvent is distilled off under reduced pressure. The residue thus obtained is purified by silica gel column chromatography [eluent; n-hexane:ethyl acetate=5:1] to obtain 1.24 g of 5-(2,4-diisobutoxybenzoyl)-2-isobutoxyphenyl acetate as a yellow oily product.
