Reaction Steps

To a solution of ((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 (180 mg, 0.15 mmol) in MeOH (5 mL) was hydrogenated in an H-Cube apparatus using a 10% (w/w) Pd/C cartridge with a flow rate of 1.0 mL/min at RT. The resulting eluent was concentrated in vacuo and the product was purified by column chromatography using an Isco Gold reversed phase silica cartridge (100% CH2Cl2 to 90:9:1 CH2Cl2:MeOH:conc. NH4OH) to provide the title compound as a white solid.
