Procedure
To a solution of (S)-2-tert-butyl 3-ethyl 8-(2-amino-6-((R)-1-(2,5-dibromophenyl)-2,2,2-trifluoroethoxy)pyrimidin-4-yl)-2,8-diazaspiro[4.5]decane-2,3-dicarboxylate (660 mg, 0.95 mmol) in dioxane (12 mL) was added phenyl boronic acid (290 mg, 2.4 mmol), Pd2(dppf)Cl2 (70 mg, 0.095 mmol), and Na2CO3 (6.0 mL, 2.0 M, aq). The reaction mixture was heated to 90° C. for 2 h, then cooled to RT, concentrated in vacuo, and extracted with CH2Cl2. The combined organic layers were washed with brine, and dried over Na2SO4. Purification by normal phase silica gel column (EtOAc/heptane) provided (S)-2-tert-butyl 3-ethyl 8-(6-((R)-1-([1,1′:4′,1″-terphenyl]-2′-yl)-2,2,2-trifluoroethoxy)-2-aminopyrimidin-4-yl)-2,8-diazaspiro[4.5]decane-2,3-dicarboxylate as a white solid.
