Reaction Steps

To a solution of (R)-4-(1-(4-bromo-2-(3-methyl-1H-pyrazol-1-yl)phenyl)-2,2,2-trifluoroethoxy)-6-chloro-2-methylpyrimidine (21 g) in dioxane (200 ml) was added (S)-2-benzyl 3-ethyl 2,8-diazaspiro[4.5]decane-2,3-dicarboxylate (15 g) and Na2CO3 (14 g). The reaction was heated to 90° C. for 48 h, then cooled to RT, filtered, and concentrated in vacuo. Purification of the residue on normal phase column chromatography on silica gel (EtOAc/heptane) provided (S)-2-benzyl 3-ethyl 8-(6-((R)-1-(4-bromo-2-(3-methyl-1H-pyrazol-1-yl)phenyl)-2,2,2-trifluoroethoxy)-2-methylpyrimidin-4-yl)-2,8-diazaspiro[4.5]decane-2,3-dicarboxylate as an off-white solid.
