To a solution of {(S)-1-[(S)-1-(2-chloro-6-fluoro-phenylcarbamoyl)-3,4-dihydro-1H-isoquinoline-2-carbonyl]-2-methyl-propyl}-carbamic acid tert-butyl ester (47 mg, 93.3 μmol, Eq: 1.00) in CH2Cl2 (3 mL) was added TFA (1 mL) dropwise. The reaction was stirred at RT for 1 h. The mixture was evaporated to provide (S)-2-((S)-2-amino-3-methyl-butyryl)-1,2,3,4-tetrahydro-isoquinoline-1-carboxylic acid (2-chloro-6-fluoro-phenyl)-amide trifluoroacetate which was used without further purification.
