Procedure

To a solution of (S)-2-tert-butyl 3-ethyl 8-(2-amino-6-((R)-1-(2-bromo-4-chlorophenyl)-2,2,2-trifluoroethoxy)pyrimidin-4-yl)-2,8-diazaspiro[4.5]decane-2,3-dicarboxylate (600 mg, 0.89 mmol) in dioxane (12 mL) was added (3-(methylsulfonyl)phenyl)boronic acid (275 mg, 1.3 mmol), Pd2(dppf)Cl2 (65 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, and concentrated in vacuo. The residue was taken up in CH2Cl2, washed with brine, and dried over Na2SO4. Purification by normal phase silica gel column (EtOAc/heptane) provides (S)-2-tert-butyl 3-ethyl 8-(2-amino-6-((R)-1-(5-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.
