Procedure

To a solution of (3S)-2-benzyl 3-ethyl 8-(2-amino-6-(1-(4-cyano-2-(3-methyl-1H-pyrazol-1-yl)phenyl)-2,2,2-trifluoroethoxy)pyrimidin-4-yl)-2,8-diazaspiro[4.5]decane-2,3-dicarboxylate (0.35 g, 0.50 mmol, see Ex. 14) in MeOH (5 mL) and water (1 mL) was added LiOH—H2O (0.20 g, 5 mmol). The mixture was heated to 50° C. overnight. The reaction was then cooled to RT, and the reaction was acidified with 6N HCl to pH=1. Concentration in vacuo followed by reverse phase HPLC purification (MeOH/water/HOAc) provided (3S)-8-(2-amino-6-(1-(4-carboxy-2-(3-methyl-1H-pyrazol-1-yl)phenyl)-2,2,2-trifluoroethoxy)pyrimidin-4-yl)-2-((benzyloxy)carbonyl)-2,8-diazaspiro[4.5]decane-3-carboxylic acid as a white solid.
