Procedure

To a solution of (S)-ethyl 8-(2-amino-6-((R)-1-(3′,4′-dimethyl-3-(3-methyl-1H-pyrazol-1-yl)-[1,1′-biphenyl]-4-yl)-2,2,2-trifluoroethoxy)pyrimidin-4-yl)-2,8-diazaspiro[4.5]decane-3-carboxylate (50 mg, 0.08 mmol) from Step 2 in THF (2.0 mL) and water (0.2 mL), was added lithium hydroxide monohydrate (58 mg, 0.05 mmol). The reaction mixture was stirred at RT for 2 h, then the solution was neutralized with 1 N HCl and concentrated in vacuo. Purification by normal phase silica gel column (EtOAc/heptane) provided the title compound as an off-white solid as the zwitterionic form.
