실험 절차

Ethyl 5-(8-chloro-2,6-dioxo-3-pentyl-2,3,6,7-tetrahydro-1H-purin-1-yl)pentanoate (70 mg, 0.19 mmol) was dissolved in EtOH. The solution was treated with a 21% solution of NaOEt in EtOH (78 μl, 0.21 mmol) and (1Z)-2-(2,6-dichlorophenyl)-N-hydroxyethanimidamide (46 mg, 0.21 mmol). The reaction was heated in the microwave at 140° C. for 10 min. The mixture was partitioned between EtOH and 2M HCl (aq). The organic layer was decanted off and concentrated by nitrogen blowdown. The crude product was purified on the MDAP. The product fractions were combined and concentrated to give the title compound as a white solid (80 mg, 80%).
