1M Hydrochloric acid (182 ml) was added to a stirred solution of methyl 3-(4-formylphenyl)propanoate ethylenedioxy acetal (16 g, 68 mmole, from example 33) in tetrahydrofuran (1100 ml) at 0° C. and the mixture stirred overnight at room temperature. The acid was neutralised and the product was extracted into ether. Evaporation of the dried (MgSO4) extracts gave 10.54 g (81%) of the title compound as an oil, νmax (film) 1735, 1700, 1605 cm-1, which was used without further purification.
