실험 절차

Isopropyl 5-ethenyl-2-hydroxybenzoate was reacted with 4-iodo-N-(2-pyridinyl)benzenesulfonamide similarly to the procedure of Example 5c. After the reaction, the solvent was evaporated, toluene was added and the suspension filtered and washed with toluene. After drying on the filter and washing with water the material was hydrolyzed and precipitated similarly to the procedure of Example 3c. Yield 40%
