Reaction Steps

tert-Butyl (2R)-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}sulfonyl)-2-(hydroxymethyl)piperazine-1-carboxylate (Example 49c, 0.537 g) was dissolved in DCM (10 mL) and treated with trifluoroacetic acid (3 mL). The reaction mixture was diluted with toluene (5 mL) and evaporated under reduced pressure.
