1-Ethyl-3-(3'-dimethylaminopropyl)carbodiimide → HCID 21997505, compound

Participants

Reaction Steps

To a solution of 2-amino-4′-bromoacetophenone hydrochloride (5.0 g), 4-heptyloxybenzoic acid (4.72 g) and 1-hydroxybenzotriazole (2.7 g) in dichloromethane (50 ml) was added 1-ethyl-3-(3′-dimethylaminopropyl)carbodiimide (WSCD) (3.65 ml) and the mixture was stirred for 3 hours at ambient temperature. The reaction mixture was diluted with dichloromethane (200 ml), and washed with water, 1N hydrochloric acid, saturated sodium hydrogen carbonate aqueous solution and brine. 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-heptyloxybenzoylamino)-4′-bromoacetophenone (6.73 g).
