Procedure

To a stirred solution of 7-(4-(2-(tert-butoxycarbonyl)-1,2,3,4-tetrahydroisoquinolin-7-ylcarbamoyl)phenoxy)-6-cyanochroman-4-carboxylic acid (40 mg, 0.070 mmol) in dioxane (1 mL) at ambient temperature was added a 4M solution of hydrogen chloride in dioxane (2 mL). The resulting solution was stirred at ambient temperature for 90 minutes. Some dark material had separated from the cloudy reaction mixture, and the supernatant was concentrated to afford 6-cyano-7-(4-(1,2,3,4-tetrahydroisoquinolin-7-ylcarbamoyl)phenoxy)chroman-4-carboxylic acid hydro-chloride as a light tan solid (30 mg, 84% yield). MS (apci) m/z=470.2 (M−Cl).
