Acid-catalyzed condensation of dipyrrolylmethane (I) with 3,5-dimethoxybenzaldehyde (II) gives rise to the porphyrin derivative (III). Subsequent demethylation of the methoxy groups of (III) employing BBr3 affords the tetraphenol compound (IV). Finally, partial reduction of (IV) by means of p-toluenesulfonyl hydrazide in hot pyridine furnishes the title compound (1,2).
