The reaction mixture was heated to reflux for 12 h, then cooled to RT, and concentrated in vacuo. Purification by normal phase chromatography (CH2Cl2/MeOH) provided 2-benzyl 3-ethyl 8-(4-amino-6-((naphthalen-2-ylmethyl)amino)-1,3,5-triazin-2-yl)-2,8-diazaspiro[4.5]decane-2,3-dicarboxylate as a white solid.
