Procedure

To a solution of 2-(2-acetoxybenzamido)-5,5,7,7-tetramethyl-5,7-dihydro-4H-thieno[2,3-c]pyran-3-carboxamide (200 mg, 0.48 mmol) in 4 mL of MeOH/dioxane=1:1, cooled to 0° C., is added potassium carbonate (66 mg, 0.52 mmol). The reaction mixture is stirred at room temperature for 90 min, filtered off and filtrate is then acidified with 1M HCl. A precipitate is formed which is separated by filtration to afford the desired compound which is used as such.
