실험 절차

The chlorin-e6 tetramethyl ester prepared in Example 2 (50 mg) was reacted with HBr/acetic acid and n-hexyl alcohol as described in Example 1 for methyl pheophorbide. The desired product was isolated in 68% yield, and the purity confirmed by TLC and HPLC. The structure was confirmed by NMR and mass spectroscopy; the spectra also showed evidence for aggregation of two chlorin units.
