実験手順

To a solution (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 (500 mg, 0.65 mmol) in DMF (10 mL) was added tributyl(prop-1-enyl)stannane (258 mg, 0.78 mmol), Pd(t-Bu3P)2 (33 mg, 0.065 mmol), and CsF (217 mg, 1.43 mmol). The reaction was heated to 130° C. in a sealed tube for 3 h, then cooled to RT, and partitioned between water and CH2Cl2. The combined organic layers were washed with brine, dried over Na2SO4, filtered, and concentrated in vacuo. Purification by normal phase silica gel column (EtOAc/heptane) provided (S)-2-tert-butyl 3-ethyl 8-(2-amino-6-((R)-2,2,2-trifluoro-1-(3′-(methylsulfonyl)-5-((E)-prop-1-en-1-yl)-[1,1′-biphenyl]-2-yl)ethoxy)pyrimidin-4-yl)-2,8-diazaspiro[4.5]decane-2,3-dicarboxylate as a white solid.
