A mixture of 4-((4-Bromophenoxy)methyl)-6-chloropyrimidin-2-amine (454 mg, 1.4 mmol), (S)-2-benzyl 3-ethyl 2,8-diazaspiro[4.5]decane-2,3-dicarboxylate (500 mg, 1.44 mmol) and NaHCO3 (605 mg, 7 mmol) in dioxane (5 mL) was heated to 100° C. for 12 h. The reaction was cooled to RT, concentrated in vacuo, and extracted with EtOAc. The combined organic layers were washed with brine, dried over Na2SO4, and concentrated in vacuo. Purification on normal phase silica gel (EtOAc/petroleum ether) provided (S)-2-benzyl 3-ethyl 8-(2-amino-6-((4-bromophenoxy)methyl)pyrimidin-4-yl)-2,8-diazaspiro[4.5]decane-2,3-dicarboxylate as a white solid.
