Reaction Steps

A solution of 1,1-dimethylethyl (2-{4-[(2S,4R)-1-acetyl-2-methyl-4-(phenylamino)-1,2,3,4-tetrahydro-6-quinolinyl]-1H-pyrazol-1-yl}ethyl)methylcarbamate (for a preparation see intermediate 54) (104 mg, 0.206 mmol) in dichloromethane (DCM) (3 mL) at room temperature under nitrogen was treated with trifluoroacetic acid (TFA) (0.5 mL, 6.49 mmol) and the resulting mixture was stirred at this temperature for 1 h then concentrated in vacuo to give (2S,4R)-1-acetyl-2-methyl-6-{1-[2-(methylamino)ethyl]-1H-pyrazol-4-yl}-N-phenyl-1,2,3,4-tetrahydro-4-quinolinamine trifluoroacetate (99 mg, 0.191 mmol, 93% yield) as a brown solid.
