4-(Adamantan-1-ylmethoxy)-6-chloro-pyrimidin-2-ylamine (89 mg, 0.30 mmol), (S)-2-benzyl 3-ethyl 2,8-diazaspiro[4.5]decane-2,3-dicarboxylate (157 mg, 0.45 mmol) and NaHCO3 (76 mg, 0.9 mmol) were dissolved in dioxane (1.5 mL) and heated to 95° C. for 64 h. Then the reaction was cooled to RT, quenched with water, and extracted with EtOAc. The organic layers were washed with brine, dried over Na2SO4, filtered, and concentrated in vacuo. Purification by normal phase silica gel column (EtOAc/heptane) provides (S)-2-benzyl 3-ethyl 8-(6-(adamantan-1-ylmethoxy)-2-aminopyrimidin-4-yl)-2,8-diazaspiro[4.5]decane-2,3-dicarboxylate as a white solid.
