| Product | 1-Butanone, 1,1'-(9H-fluorene-2,7-diyl)bis(4-(1-piperidinyl)-, dihydrochloride | HCID 169647 | — |
Reaction Steps
By the procedure of Example 28, 2,7-bis(4-piperidinobutyryl)fluorene is prepared and dissolved in a chloroformbutanone mixture. The resulting solution is acidified with ethereal HCl, and the solid precipitate recrystallized three times from methanol-butanone to give 2,7-bis(4-piperidinobutyryl)fluorene dihydrochloride, M.P. 286°-288° C.
