It was passed through a column (diameter 25mm) packed with silica gel (Wakogel C-200°10CI'). First, 750 mA' of ethylene chloride was eluted, then 600 ml of a mixed solvent of ethylene chloride and ethyl acetate in a volume ratio of 9:1, and then 120 mA of a mixed solvent of ethylene chloride and ethyl acetate in a volume ratio of 9:1.
The solution obtained by elution with m1 was concentrated under reduced pressure to obtain 5-(
P-phenyl)-4-phenyl-2,ro,6,7-titrahydro-6-(P-tolyl)-2,5,7-)dioxo-5H-pyrrolo(sea-a':+pyrimidine crystals 0. 43f (19%) was obtained. This was recrystallized from a mixed solvent of ethanol and acetonitrile to give a decomposition point of 9 from 627 to
Yellow prismatic crystals having a temperature of 0°C were obtained. The elemental analysis values are shown below.
