Participants

Reaction Steps

To a suspension of 50 mg 4-(4-aminophenyl)pyrrolo[1,2-d][1,2,4]triazin-1(2H)-one (0.22 mmol) in 1 ml tetrahydrofuran at room temperature a solution of 0.03 ml pyridine (0.3 mmol) in 0.5 ml of tetrahydrofuran was added over 5 minutes. Subsequently, 0.03 ml phenylchlorformate (0.23 mmol) dissolved in 3 ml of tetrahydrofuran was added over 30 minutes and the reaction was stirred at room temperature overnight. The solvent was evaporated on vacuo and the mixture was directly incorporated on silica by dichloromethane. The mixture was purified by silica gel chromatography (4 g, cyclohexane:ethylacetate gradient) to afford crude material which was purified by column chromatography (cyclohexane:ethylacetate gradient) to afford the title compound.
