反应详情

1500 ml of a solution of 20 g of 2,6-dimethoxybenzaldehyde in propionic acid was heated at 100° C. with stirring, 8.05 g of pyrrole was added and the mixture was continuously heated with stirring for 7 hours. After cooling to room temperature, the mixture solution was left overnight. The reaction solution was filtered through a glass filter, and the filtrate was washed with cooled methanol and purified with a silica gel column (dichloromethane) to obtain 5,10,15,20-tetra(2',6'-dimethoxyphenyl)porphyrin.
