5.00 g (27.1 mmol) of methyl 2-acetyl-6-heptenoate (Example 20A) are introduced into 50 ml of methanol and ice-cooled. 0.56 g (14.9 mmol) of sodium borohydride are added in portions and the mixture is stirred for a further 1 h. The batch is then evacuated from the solvent, taken up in diethyl ether and washed with 1 N hydrochloric acid. The organic phase is dried, concentrated and flash-chromatographed using the eluent petroleum ether/ethyl acetate 10/1.
