Participants

Reaction Steps

To a stirred solution of 1.21 g of ethyl (1-trityl-1H-tetrazol-5-yl)acetate in ethanol (6mL)-tetrahydrofuran (6 mL) was added 1.67 mL of 2 mol/L sodium hydroxide solution under ice-cooling, and the mixture was stirred at room temperature for an hour. To the reaction mixture were added ethyl acetate and 10 mL of 1 mol/L hydrochloric acid, and the mixture was separated. After being washed with water, and brine, the organic layer was dried over anhydrous magnesium sulfate, and the solvent was removed under reduced pressure to give 1.32 g of (1-trityl-1H-tetrazol-5-yl)acetic acid.
