Procedure

A solution of 0.20 g (0.56 mmol) of the compound from Example IX in 5 ml of isopropanol is heated together with 0.11 g (0.56 mmol) of the compound from Example VI and 0.06 g (0.67 mmol) of sodium acetate under reflux for 2 hours. The reaction mixture is concentrated, and the residue is taken up in ethyl acetate and extracted with dilute hydrochloric acid. The aqueous phase is made alkaline with dilute sodium hydroxide solution and extracted with ethyl acetate. The organic phase is dried over sodium sulfate and concentrated. The residue is chromatographed on silica gel with cyclohexane/ethyl acetate (5:1→3:1) as mobile phase.
