실험 절차

To a solution of the compound 26 (300 mg, 0.761 mmol) in methanol (1 ml) was added a solution of potassium hydroxide (111 mg, 1.99 mmol) in methanol (1 ml) under ice-cooling, and a solution of iodine (251 mg, 1.00 mmol) in methanol (4 ml) was further added, followed by stirring at the same temperature for 1 hour. To the reaction solution were added a 5% aqueous sodium hydrogen sulfite solution and water, and precipitated crystals were collected by filtration. Methyl 4-benzyloxy-5-(4-fluorobenzylcarbamoyl)-3-methoxypyridine-2-carboxylate 27 (275 mg, 85%) was obtained as a colorless crystal.
