A convenient procedure for the synthesis of 5-(4-acetamidophenyl)- 10,15,20-tris(4-substituted phenyl) porphyrins (5-8) from dipyrromethane is reported, meso-(4-Substituted phenyl) dipyrromethanes (1-4) were obtained in yields of 72-84% by the reaction of 4-substituted benzaldehyde with an excess of pyrrole. The porphyrins (5-8) were isolated with appreciable yields of 15- 17%.
