Procedure

To a solution of (S)-8-(2-amino-6-((R)-1-(4-bromo-2-(3-methyl-1H-pyrazol-1-yl)phenyl)-2,2,2-trifluoroethoxy)pyrimidin-4-yl)-2-((benzyloxy)carbonyl)-2,8-diazaspiro[4.5]decane-3-carboxylic acid (product of Step 3, Example 10m) (240 mg, 0.33 mmol) in ethanol (8 mL) was added (E)-ethyl 3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)acrylate (110 mg, 0.49 mmol), PdCl2(PPh3)2 (20 mg, 0.049 mmol) and KHCO3 (170 mg, 0.05 mmol). The reaction was heated to 80° C. for 2 h, cooled to RT, and filtered. The solvent was removed in vacuo. Purification via normal phase silica gel chromatography (CH2Cl2/heptane) provided ((S)-8-(2-amino-6-((R)-1-(4-((E)-3-ethoxy-3-oxoprop-1-en-1-yl)-2-(3-methyl-1H-pyrazol-1-yl)phenyl)-2,2,2-trifluoroethoxy)pyrimidin-4-yl)-2-((((2E,4Z)-2-vinylhexa-2,4-dien-1-yl)oxy)carbonyl)-2,8-diazaspiro[4.5]decane-3-carboxylic acid as a white solid.
