Subsequently, compound 1 was converted
into 5-(4-amidogen) phenyl-10,15,20-tris (3,4,5-trimethoxylphenyl)
porphyrin 2 by Tin(II) chloride dehydrate with 36% HCl. Finally,
compound 2 was treated with Zn(OAc)2, and then reacted with 4-
formyl benzoic acid by bonus-elimination reaction to give PZn-
ABIAACOOH.
