Reaction Steps
A mixture of (S)-2-tert-butyl 3-ethyl 8-(2-amino-6-((2-bromo-4-chlorobenzyl)oxy)pyrimidin-4-yl)-2,8-diazaspiro[4.5]decane-2,3-dicarboxylate (300 mg, 0.4 mmol), (3-(methylsulfonyl)phenyl)boronic acid (280 mg, 1 mmol), and Pd(dppf)Cl2 (62 mg, 0.09 mmol) in dioxane (5 mL)/aq. Na2CO3 solution (2.0 M, 5 mL) was heated to 90° C. for 4 h. The reaction was then cooled to RT, the solids filtered away, and the filtrate concentrated in vacuo. Purification on normal phase silica gel (CH2Cl2/MeOH) provided (S)-2-tert-butyl 3-ethyl 8-(2-amino-6-((5-chloro-3′-(methylsulfonyl)-[1,1′-biphenyl]-2-yl)methoxy)pyrimidin-4-yl)-2,8-diazaspiro[4.5]decane-2,3-dicarboxylate as an off-white solid.
