Procedure
To a solution of 4-chloro-6-[(1R)-1-[4-chloro-2-(3-methylpyrazol-1-yl)phenyl]-2,2,2-trifluoroethoxy]pyrimidin-2-amine (57.3 g, 137 mmol, Step 1) in dioxane (500 mL) was added (S)-2-benzyl 3-ethyl 2,8-diazaspiro[4.5]decane-2,3-dicarboxylate (48 g, 124.9 mmol), and NaHCO3 (31.5 g, 375 mmol). After 5 h, an additional amount of NaHCO3 (31.5 g, 375 mmol) was added and the reaction mixture was heated to 90° C. for 36 h. The reaction was then cooled to RT and filtered. Purification by normal phase silica gel column (EtOAc/heptane) provided (S)-2-benzyl 3-ethyl 8-(2-amino-6-((R)-1-(4-chloro-2-(3-methyl-1H-pyrazol-1-yl)phenyl)-2,2,2-trifluoroethoxy)pyrimidin-4-yl)-2,8-diazaspiro[4.5]decane-2,3-dicarboxylate as a white solid.
