Trifluoroacetic Acid (1 mL) was added to a solution of tert-butyl 4-({2-(3-{[tert-butyl(dimethyl)silyl]oxy}-2,2-dimethylpropyl)-6-[5-(cyclopropylcarbamoyl)-3-fluoro-2-methylphenyl]-1-oxo-1,2-dihydroisoquinolin-4-yl}sulfanyl)piperidine-1-carboxylate (Example 59a, 0.06 g) in DCM (2 mL), and the reaction was stirred at room temperature for 30 min. Toluene (10 mL) was added and the volatiles were removed under reduced pressure (repeated 3×). The residue was purified by preparative HPLC (Phenomenex Gemini column using a 95-5% gradient of 0.1% aqueous NH3 in acetonitrile), and after solvent removal and trituration with diethyl ether gave the title compound (0.01 g).
