To a solution of (S)-2-tert-butyl 3-ethyl 8-(2-amino-6-((R)-2,2,2-trifluoro-1-(4-isopropoxy-[1,1′:3′,1″-terphenyl]-4′-yl)ethoxy)pyrimidin-4-yl)-2,8-diazaspiro[4.5]decane-2,3-dicarboxylate (130 mg, 0.164 mmol) in CH2Cl2 (4 mL) was added TFA (1 mL), and the reaction mixture was stirred at 25° C. for 12 h. The mixture was concentrated, and neutralized to pH 7-8 with saturated aqueous NaHCO3. The aqueous layer was extracted with CH2Cl2, washed with brine, dried over Na2SO4, filtered, and concentrated in vacuo to provide (S)-ethyl 8-(2-amino-6-((R)-2,2,2-trifluoro-1-(4-isopropoxy-[1,1′:3′,1″-terphenyl]-4′-yl)ethoxy)pyrimidin-4-yl)-2,8-diazaspiro[4.5]decane-3-carboxylate as a light yellow solid that is used without further purification.
