Pyrrole was refluxed with PhCHO in DMF containing AlCl3 for 2 h, the reaction mixture was cooled to room temperature, a small amount of EtOH was added, and the mixture cooled with ice to give violet crystals of tetraphenylporphyrin. Tetrakis(p-nitrophneyl)- and tetrakis(3,4-dimethoxyphenyl)prophyrin were prepared analogously.
