Sodium ethoxide → 3-Butyl-8-chloro-1-(3-{3-[(2-chloro-4-fluorophenyl)methyl]-1,2,4-oxadiazol-5-yl}propyl)-3,7-dihydro-1H-purine-2,6-dione

Participants

Reaction Steps

Ethyl 4-(3-butyl-8-chloro-2,6-dioxo-2,3,6,7-tetrahydro-1H-purin-1-yl)butanoate (100 mg, 0.28 mmol) and (1Z)-2-(2-chloro-4-fluorophenyl)-N-hydroxyethanimidamide (62.4 mg, 0.308 mmol) and 21% by wt. ethanolic sodium ethoxide (0.157 ml, 0.42 mmol) were heated together in a microwave reactor in EtOH (1.5 ml) at 140° C. for 10 min. The mixture was worked up by partitioning between EtOAc and 2M HCl. The organic phase was evaporated and purified by MDAP to afford the title compound as a solid (73 mg).
