- Wide range of the melting point observed was caused by the concomitant isomer formation derived from the thermal equilibration between 8 and 9 on heating in a melting point apparatus. The melt was shown to be a mixture of 8 and 9 with predominance of the former on the basis of the 13C-NMR measurement.
