Procedure
t-Butyl 2,4,4-trifluorospiro[5H-thieno[2,3-c]pyran-7,4′-piperidine]-1′-carboxylate (2.00 g, 5.50 mmol) is dissolved in hydrochloric acid (4N in dioxane) (10 mL, 40 mmol). The mixture is stirred at room temperature for 1 h and then passed through a 50 g SCX cartridge (solid cation exchange) to yield 1.3 g of the title compound after evaporation of 2 N ammonia in methanol fraction. MS (m/z): 264 (M+1).
