Procedure
The compound obtained in Example 13 (50 g) and diphenylether (500 ml) were mixed and the ethanol formed as the reaction proceeded was distilled off while continuing the heating under reflux for 4 hours. After allowing to cool followed by distilling diphenylether off under reduced pressure a crude crystal was precipitated and washed with n-hexane to obtain the title compound (35.1 g, 80.6%).
