Reaction Steps

To a solution of (S)-2-tert-butyl 3-(2-(dimethylamino)ethyl) 8-(2-amino-6-((R)-1-(4-chloro-2-(3-methyl-1H-pyrazol-1-yl)phenyl)-2,2,2-trifluoroethoxy)pyrimidin-4-yl)-2,8-diazaspiro[4.5]decane-2,3-dicarboxylate (1.4 g, 1.86 mmol) in CH2Cl2 (9 mL) was added TFA (4.5 mL), and the reaction was stirred at RT for 2 h. Then the reaction was concentrated in vacuo and the residue was partitioned between CH2Cl2 and aqueous NaHCO3, and extracted. The combined organic layers were washed with brine, dried over Na2SO4, and concentrated in vacuo. Purification via prep-HPLC column chromatography (CH2Cl2/EtOH/NH4OH) provided the title compound as an off-white solid.
