Procedure

To a solution of (S)-2-tert-butyl 3-ethyl 8-(2-amino-6-((R)-1-(2-bromo-5-chlorophenyl)-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 (3-(methylsulfonyl)phenyl)boronic acid (285 mg, 1.43 mmol), Pd2(dppf)Cl2 (70 mg, 0.095 mmol) and Na2CO3 (6.0 mL, 2.0 M, aq). The reaction was heated to 90° C. for 2 h, then cooled to RT, concentrated in vacuo. The residue was taken up in CH2Cl2, washed with brine, and extracted with CH2Cl2. The combined organic layers were dried over Na2SO4. Purification by normal phase silica gel column (EtOAc/heptane) provided (S)-2-tert-butyl 3-ethyl 8-(2-amino-6-((R)-1-(4-chloro-3′-(methylsulfonyl)-[1,1′-biphenyl]-2-yl)-2,2,2-trifluoroethoxy)pyrimidin-4-yl)-2,8-diazaspiro[4.5]decane-2,3-dicarboxylate as a white solid.
