Reaction Steps

To a solution of (S)-8-(2-amino-6-((R)-1-(4-chloro-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) (300 mg, 0.412 mmol) in pyridine (1.0 mL) was added cyclobutanecarbonyl chloride (54 mg, 0.045 mmol). The reaction mixture was stirred at RT for 3 h, then diluted with EtOAc, and washed with 0.5 N HCl. The organic layer was dried over Na2SO4, filtered, and concentrated in vacuo. Purification on a 40 g Isco RediSep silica cartridge (EtOAc/heptane) provides (S)-2-benzyl 3-ethyl 8-(6-((R)-1-(4-chloro-2-(3-methyl-1H-pyrazol-1-yl)phenyl)-2,2,2-trifluoroethoxy)-2-(cyclobutanecarboxamido) pyrimidin-4-yl)-2,8-diazaspiro[4.5]decane-2,3-dicarboxylate as an off-white solid.
