Participants

Reaction Steps

The corresponding 9-ethoxy derivative is prepared by reacting a solution of bis[3-(dibutylamino)propyl] 9-hydroxyphenanthrene-2,7-dicarboxylate in methanol with diazoethane by co-distillation with ether into the reaction mixture at -10° to 30°C. After standing overnight, the crude bis[3-(dibutylamino)propyl]9-ethoxyphenanthrene-2,7-dicarboxylate so obtained is converted to its dihydrochloride salt by the addition of ethereal hydrogen chloride.
