실험 절차

To a solution of 3.8mg of Cryptophycin 1 in 1.5 mL of 2:1 1,2-dimethoxyethane/water was added 9 μL 1N HCl. The solution was allowed to stir at room temperature for 4 h, neutralized with potassium carbonate, and evaporated. The residue was partitioned between water and CH2Cl2. The CH2Cl2 -soluble material was purified by reversed-phase HPLC to obtain 3.3 mg of pure Cryptophycin 8.
