Embodiment 1

[0026] 4-N,N-Dimethylaminobenzaldehyde (1mmol) and dibromo-1,19-dideoxy-3,8,12,17-tetraethyl-2,7,13,18-tetramethyl Add biladien-a, c (1mmol) into a 250mL three-necked flask, and add ethanol (100mL) to dissolve. The solution was heated to reflux (78-82°C) under argon protection. p-Toluenesulfonic acid (2.5 g) was dissolved in ethanol (10 mL) and added slowly to the reaction mixture over 18 hours. The reaction mixture was then continued for up to 48 hours. After the reactant was cooled to room temperature, the solvent was removed under reduced pressure. The residue was dissolved in 200 mL DCM and washed with saturated NaHCO 3 The solution and distilled water were washed twice, and the aqueous layer was removed. The solvent was evaporated under reduced pressure for chromatographic separation, and the product 5-(4-N,N-dimethyl)phenyl-13,17-diethyl-2,3,7,8 was obtained after recrystallization from methanol and chloroform , 12,18-Hexamethylporphyrin (1a). Yield: 42.1%. Meltin...
