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-(tert-butoxycarbonyl)-2,8-diazaspiro[4.5]decane-3-carboxylic acid (1.6 g, 2.45 mmol) in DMF (24 mL) were added (2-chloro-ethyl)-dimethyl-amine hydrochloride (535 mg, 3.7 mmol) and K2CO3 (1.0 g, 7.4 mmol), and the reaction mixture was heated at 65° C. for 16 h. Then the reaction was cooled to RT, partitioned between EtOAc and water, and extracted. The combined organic layers were washed with brine, dried over Na2SO4, filtered, and concentrated in vacuo. Purification via prep-HPLC column chromatography (CH2Cl2/MeOH/NH4OH) provided (S)-2-tert-butyl 3-(2-(dimethylamino)ethyl) 8-(2-amino-6-((R)-1-(4-chloro-2-(3-methyl-1H-pyrazol-1-yl)phenyl)-2,2,2-trifluoroethoxy)pyrimidin-4-yl)-2,8-diazaspiro[4.5]decane-2,3-dicarboxylate as an off-white solid.
