실험 절차

A solution of (1Z)-5-(8-chloro-2,6-dioxo-3-pentyl-2,3,6,7-tetrahydro-1H-purin-1-yl)-N-hydroxypentanimidamide (50 mg, 0.13 mmol) in EtOH (1 ml) was treated with a 21% solution of NaOEt in EtOH (55 μl, 0.21 mmol) and ethyl 3-thiophenecarboxylate (18 μl, 0.13 mmol). The mixture was heated in the microwave at 150° C. for 10 min. After cooling, the reaction was partitioned between 2M HCl (aq) and EtOAc. The organic layer was separated and the aqueous extracted again with EtOAc. The combined extracts were concentrated and purified by the MDAP. The title compound was obtained as an off-white solid (20 mg, 32%).
