反応手順

0.3 ml of a 2 N aqueous sodium hydroxide solution is added to a solution of 0.6 g of 2-(5-acetylaminomethyl-2-thienyl)-acetic acid in 5 ml of dioxane. The mixture is stirred for 12 hours at 55°-60° C. and cooled to 25° C., 0.2 ml of tert.-butoxycarbonyl azide is added, the mixture is stirred for 16 hours at room temperature and 2-(5-tert.-butoxycarbonylaminomethyl-2-thienyl)-acetic acid is isolated in accordance with the process described above.
