Procedure

To a solution of (S)-2-benzyl 3-ethyl 8-(2-amino-6-((R)-2,2,2-trifluoro-1-(4-formyl-2-(3-methyl-1H-pyrazol-1-yl)phenyl)ethoxy)pyrimidin-4-yl)-2,8-diazaspiro[4.5]decane-2,3-dicarboxylate (36 mg, 0.05 mmol) in dichloroethane (2 mL) was added NaCNBH3 (1M in THF, 1 mL, 0.5 mmol), followed by a few drops of HOAc. The mixture was stirred at RT for 3 h then concentrated in vacuo. The residue was dissolved in MeOH and purified on reverse phase HPLC (MeOH/H2O/HOAc) to provide (S)-2-benzyl 3-ethyl 8-(2-amino-6-((R)-2,2,2-trifluoro-1-(4-(hydroxymethyl)-2-(3-methyl-1H-pyrazol-1-yl)phenyl)ethoxy)pyrimidin-4-yl)-2,8-diazaspiro[4.5]decane-2,3-dicarboxylate as a sticky solid that was used without further purification.
