Reaction Steps

A solution of (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 (240 mg, 0.4 mmol, Step 3) in EtOAc (5 mL) was hydrogenated using an H-Cube apparatus and a 10% (w/w) Pd/C cartridge with a flow rate of 1.0 mL/min at RT. Purification on normal phase silica gel (EtOAc/heptane) provided (S)-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-3-carboxylate.
