Reaction Steps

To a solution of (S)-2-tert-butyl 3-ethyl 8-(2-amino-6-((5-chloro-3′-(methylsulfonyl)-[1,1′-biphenyl]-2-yl)methoxy)pyrimidin-4-yl)-2,8-diazaspiro[4.5]decane-2,3-dicarboxylate (200 mg, 0.25 mmol) in CH2Cl2 (5 ml) was added TFA (3 mL), and the resulting mixture was stirred at RT for 1 h. The reaction mixture was concentrated in vacuo, and the residue was partitioned between CH2Cl2 and saturated NaHCO3. The organic layer was dried over Na2SO4, filtered, and concentrated in vacuo. Purification by prep-TLC (CH2Cl2/MeOH) provided (S)-ethyl 8-(2-amino-6-((5-chloro-3′-(methylsulfonyl)-[1,1′-biphenyl]-2-yl)methoxy)pyrimidin-4-yl)-2,8-diazaspiro[4.5]decane-3-carboxylate as an off-white solid.
