To a solution of (S)-2-tert-butyl 3-ethyl 8-(2-amino-6-((R)-2,2,2-trifluoro-1-(3′-(methylsulfonyl)-4-(prop-1-en-1-yl)-[1,1′-biphenyl]-2-yl)ethoxy)pyrimidin-4-yl)-2,8-diazaspiro[4.5]decane-2,3-dicarboxylate (200 mg, 0.26 mmol) in EtOH (10 mL) was added 10% Pd/C (200 mg) and the reaction mixture was stirred under 1 atm H2 for 12 h. The solids were filtered and the filtrate was concentrated to afford (S)-2-tert-butyl 3-ethyl 8-(2-amino-6-((R)-2,2,2-trifluoro-1-(3′-(methylsulfonyl)-4-propyl-[1,1′-biphenyl]-2-yl)ethoxy)pyrimidin-4-yl)-2,8-diazaspiro[4.5]decane-2,3-dicarboxylate as a white solid that is used directly without further purification.
