Reaction Steps

A 25 mL flask was charged with methyl 2-((R)-(5-chloro-2-methylphenyl)((R)-1-((S)-2-(Boc-methylamino)-3-((R)-tetrahydro-2H-pyran-3-yl)propylcarbamoyl)piperidin-3-yl)methoxy)ethylcarbamate (60 mg, 0.094 mmol). 20% TFA/CH2Cl2 solution (8 mL) was added and stirred for 0.5 h at 0° C. The mixture was concentrated to give the residue, which was purified by preparative HPLC to give the desired product methyl 2-((R)-(5-chloro-2-methylphenyl)((R)-1-((S)-2-(methylamino)-3-((R)-tetrahydro-2H-pyran-3-yl)propylcarbamoyl)piperidin-3-yl)methoxy)ethylcarbamate (4.35 mg, 9%) as its TFA salt. 1H-NMR (MeOD): 1.25 (m, 2H), 1.35-1.50 (m, 4H), 1.60-1.80 (m, 3H), 1.95 (m, 2H), 2.35 (s, 3H), 2.75 (s, 3H), 3.65 (s, 3H), 3.85 (m, 4H), 4.45 (d, 1H), 7.15 (m, 2H), 7.30 (s, 1H).
