Reaction Steps
Following the procedure of Example 42, only substituting for 2,7-bis(4-piperidinobutyryl)xanthene, 25.8 g (0.05 mole) 2,7-bis(5-piperidinovaleryl)xanthene and using 600 ml of glacial acetic acid and 19.7 g (0.066 mole) sodium dichromate, the solid obtained is recrystallized from a benzene-heptane mixture to give the title compound, M.P. 109°-110°C.
