1-Hydroxybenzotriazole → HCID 18331075, compound

Participants

Reaction Steps

To a solution of 2-amino-4′-ethoxycarbonylacetophenone hydrochloride (700 mg), 4-(4-propoxyphenyl)benzoic acid (866 mg) and 1-hydroxybenzotriazole (456.5 mg) in triethylamine (0.47 ml) and dichloromethane (7 ml) was added 1-ethyl-3-(3′-dimethylaminopropyl)carbodiimide hydrochloride (WSC.HCl) (648 mg), and stirred for 5 hours at ambient temperature. To the reaction mixture was added water (100 ml), and extracted with dichloromethane. The organic layer was washed with 1N hydrochloric acid, water, saturated sodium hydrogen carbonate aqueous solution and brine. Then the organic layer was dried over magnesium sulfate. Magnesium sulfate was filtered off, and the filtrate was evaporated under reduced pressure. The solids were slurried in ethyl acetate, and collected by filtration to give 2-[4-(4-propoxyphenyl)benzoylamino]-4′-ethoxycarbonylacetophenone (746 mg).
