Abstract: Objective To optimize the synthesis of photosensitizer chlorine e₆-C₁₅ monomethyl ester (1). Methods Target compound 1 was synthesized through E ring cracking of pheophorbide a (3) in methanol solution of potassium hydroxide followed by adding H₂O for ester hydrolysis with "one-pot" process. Four main factors that influencing the synthetic yield of target compound 1 are ring cleavage reaction time (A), reflux hydrolysis reaction time (B), alkali concentration (C) and weight ratio of material 3 to alkali (D). Each of the four factors was chosen at three levels and evaluated by the orthogonal experimental design of L₉(3⁴). Results The optimization terms of the synthesis of target compound 1 were B₁C₂A₂D₁. The yield of compound 1 was raised from 43.0% to 56.5%. Conclusion The developed process has the advantages of simple operation, good safety and high reaction yield, and is suitable for industrial production.
