Procedure

To a stirred solution of tert-butyl 7-(4-(6-cyano-4-(methoxycarbonyl)chroman-7-yloxy)benzamido)-3,4-dihydroisoquinoline-2(1H)-carboxylate (84 mg, 0.14 mmol) in a mixture of methanol (1 mL) and tetrahydrofuran (0.5 mL) was added 2M sodium hydroxide (0.36 mL, 0.72 mmol). The resulting solution was stirred at ambient temperature for 1 hour, then concentrated. The residue was partitioned between ethyl acetate (10 mL) and 1M hydrochloric acid (5 mL). The organic layer was dried over sodium sulfate and concentrated to afford 7-(4-(2-(tert-butoxycarbonyl)-1,2,3,4-tetrahydroisoquinolin-7-ylcarbamoyl)phenoxy)-6-cyanochroman-4-carboxylic acid as an orange oil (40 mg, 49% yield).
