実験手順
688 mg of the compound of Example 51A with 76% purity (1.23 mmol) are provided in 29 ml of tetrahydrofuran and, at room temperature, 389 mg (16.2 mmol) of lithium hydroxide and 10 ml of water are added. The mixture is stirred at room temperature for 5 h, a 1N aqueous hydrogen chloride solution is subsequently added until the pH is acidic, and the mixture is extracted with ethyl acetate, dried over sodium sulfate, filtered and concentrated. The residue is stirred in a little cyclohexane and the precipitate is collected by suction filtration. 413 mg (83% of theory) of the title compound are obtained.
