Ethyl 3-(methylamino)propanoate → HCID 59529304, compound

Participants

Reaction Steps

A solution of 4-({cyclohexyl[2-methyl-5-(pyridin-3-yl)furan-3-yl]methyl}amino)benzoic acid (586 mg), ethyl 3-(methylamino)propanoate (236 mg), 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (345 mg), hydroxybenzotriazole monohydrate (276 mg) and triethylamine (250 μl) in N,N-dimethylformamide (10 mL) was stirred at room temperature for 4 hr. Ethyl acetate was added, the mixture was washed with saturated aqueous sodium hydrogen carbonate solution and water, and the organic layer was dried over magnesium sulfate. The solvent was evaporated under reduced pressure, and the organic layer was dried over magnesium sulfate. The solvent was evaporated under reduced pressure. To the residue were added ethanol (3 mL), tetrahydrofuran (3 mL) and 1N lithium hydroxide (3.0 mL), and the mixture was stirred at room temperature for 1 hr. The solvent was evaporated under reduced pressure, and water (10 mL) was added. The mixture was neutralized with 1N hydrochloric acid under ice-cooling, and stirred for 1 hr. The resulting precipitate was collected by filtration and dried to give the title compound (544 mg, 88%).
