Reaction Steps

To a solution of 10 mg of Cryptophycin 1 in 1 mL dry methanol was added 10 μL methanolic HCl (obtained by treating 1.25 g thionyl chloride with 25 mL MeOH). After stirring for 4 h the solvent was removed in vacuo and the sample was left under vacuum for 12 h. Reversed-phase HPLC gave 8 mg of pure Cryptophycin 9.
