Procedure

To a solution of 4-[(1R)-1-[4-bromo-2-(3-methylpyrazol-1-yl)phenyl]-2,2,2-trifluoro-ethoxy]-6-chloro-pyrimidin-2-amine (125 mg, 0.3 mmol, Step 1) in dioxane (3 mL) was added (S)-2-benzyl 3-ethyl 2,8-diazaspiro[4.5]decane-2,3-dicarboxylate (95 mg, 0.3 mmol) and Na2CO3 (182 mg, 0.35 mmol). The reaction was heated to 90° C. for 130 h, then cooled to RT, filtered, and concentrated in vacuo. Purification by normal phase silica gel column (EtOAc/heptane) provided (S)-2-benzyl 3-ethyl 8-(2-amino-6-((R)-1-(4-bromo-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.
