Participants

Reaction Steps

944 mg (2.14 mmol) of the ester obtained in Example 3, dissolved in 30 ml of a methanol/tetrahydrofuran (1/1) mixture, were treated with 81 mg of sodium borohydride. The reaction mixture was stirred for 5 hours at room temperature. Evaporation was carried out to dryness, the residue was taken up in ether and this phase was washed to neutral pH. After drying and evaporating, 905 mg (96%) of the expected compound, melting at 140°-141° C., were isolated.
