Reaction Steps

To a solution of (S)-8-(2-amino-6-((R)-1-(5-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) (180 mg, 0.24 mmol) in ethanol (2 mL) was added Pd(PPh3)2Cl2 (34 mg, 0.048 mmol), KHCO3 (242 mg, 2.4 mmol). A balloon of CO was fitted and the reaction mixture was heated to 80° C. for 20 h, then cooled to RT. The reaction was quenched with water, and extracted with EtOAc. The combined organic layers were washed with brine, dried over MgSO4, filtered, and concentrated in vacuo. Purification by normal phase silica gel column (CH2Cl2/MeOH/AcOH) provided (S)-8-(2-amino-6-((R)-1-(5-(ethoxycarbonyl)-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 as an off-white solid.
