반응 단계
(R)-2-chloro-8-cyclopentyl-7-ethyl-7,8-dihydropteridin-6-amine (177 mg, 0.64 mmol) in MeOH (1.5 mL) treated with 50% aqueous chloroacetaldehyde (131 μL, 1.3 Eq.) and the reaction mixture heated to reflux for 6 hours. A further portion of 50% aq. chloroacetaldehyde (400 μL, 3.0 Eq.) was added, and the reaction mixture heated to 68° C. overnight. NaHCO3 (aq. sat.) and EtOAc was added, and the aqueous was further extracted with EtOAc. The combined organic extracts were dried over MgSO4, filtered and concentrated in vacuo.
