실험 절차

A suspension of the product obtained in Step A of Example 16 (300 mg, 0.76 mmol), 111 mg (0.99 mmol) of 3-furanboronic acid, 137 mg (0.99 mmol) of K2CO3 and 45 mg (0.038 mmol) of tetrakistriphenylphosphine in a mixture of 6 ml of ethanol and 1.8 ml of water is heated at 80° C. for 3 hours under N2. The ethanol is evaporated off in vacuo and the residue is taken up in water and 1N HCl. The precipitate is filtered off to yield the title product.
