Reaction Steps

To a solution of 2-((benzyloxy)carbonyl)-8-(6-((R)-1-(4-chloro-2-(3-methyl-1H-pyrazol-1-yl)phenyl)-2,2,2-trifluoroethoxy)-2-(methylsulfonyl)pyrimidin-4-yl)-2,8-diazaspiro[4.5]decane-3-carboxylic acid (300 mg, 0.393 mmol) in 1,4-dioxane (10 mL) was added phenol (74 mg, 0.79 mmol), Cs2CO3 (512 mg, 1.5 mmol), and the reaction was heated to 70° C. for 21 h. The reaction was then cooled to RT, diluted with water, acidified to pH<1 with 1 N HCl, and extracted with EtOAc. The combined organic layers were dried over Na2SO4, filtered, and concentrated in vacuo. Purification on a 50 g Isco Gold RediSep reverse phase silica cartridge (H2O:HOAc: 99:1 MeOH:HOAc 99:1) provided 2-((benzyloxy)carbonyl)-8-(6-((R)-1-(4-chloro-2-(3-methyl-1H-pyrazol-1-yl)phenyl)-2,2,2-trifluoroethoxy)-2-phenoxypyrimidin-4-yl)-2,8-diazaspiro[4.5]decane-3-carboxylic acid as an off-white solid.
