Procedure

A 25 ml round-bottom flask was charged with 1-{4-[(2R,4S)-4-((3,5-bis-trifluoromethyl-benzyl)-{5-[1-(tetrahydro-pyran-2-yl)-1H-pyrazol-4-yl]-pyrimidin-2-yl}amino)-2-ethyl-pyrrolidin-1-yl]-5-chloro-pyrimidin-2-yl}-piperidine-4-carboxylic acid ethyl ester (70 mg, 0.084 mmol), 1N HCl (0.8 ml, 0.8 mmol) and MeOH (2 ml). The mixture is then heated to 60 degree for 30 minutes. After cooling down to rt, Saturated NaHCO3 and dichloromethane are added, then organic layer is collected. Removal of solvent give 1-[4-((2R,4S)-4-{(3,5-bis-trifluoromethyl-benzyl)-[5-(1H-pyrazol-4-yl)-pyrimidin-2-yl]-amino}-2-ethyl-pyrrolidin-1-yl)-5-chloro-pyrimidin-2-yl]-piperidine-4-carboxylic acid ethyl ester and it is used for the next step without further purification.
