Versuchsvorschrift
0.5 g of the compound from Example 11 is heated to 240° C. for one hour in 5 ml of diphenyl ether. The residue remaining after distilling off the solvent consists of 0.3 g of crude product of melting point 208°-10° C. Recrystallization from ethanol gives a melting point of 226°-28°.
