Procedure

To a solution of (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 (300 mg, 0.4 mmol, Step 2) in ethanol (2 mL) and water (0.5 mL) was added phenylboronic acid (143 mg, 0.8 mmol), PdCl2(PPh3)2 (41 mg, 0.058 mmol), and Cs2CO3 (390 mg, 1.2 mmol). The reaction was heated to 60° C. for 16 h, then cooled to RT, filtered through celite and concentrated in vacuo. Purification by normal phase silica gel column (EtOAc/heptane) provided (S)-2-benzyl 3-ethyl 8-(2-amino-6-((R)-2,2,2-trifluoro-1-(3-(3-methyl-1H-pyrazol-1-yl)-[1,1′-biphenyl]-4-yl)ethoxy)pyrimidin-4-yl)-2,8-diazaspiro[4.5]decane-2,3-dicarboxylate as a white solid.
