Triethylamine → Ethyl 3-[3-([2-(diethoxyphosphoryl)propanoyl]aminomethyl)-4-methoxyphenyl]-2-isopropoxypropionate

Participants

Reaction Steps

643 mg of 2-diethylphosphonopropionic acid and 973 mg of ethyl 3-[3-(aminomethyl)-4-methoxyphenyl]-2-isopropoxypropionate were dissolved in 10 ml N,N-dimethylformamide, and 470 μl diethyl cyanophosphonate and 1.07 ml triethylamine were successively added thereto. The mixture was stirred overnight at room temperature, and the reaction mixture was diluted with ethyl acetate. The organic layer was washed with water and brine, dried over anhydrous magnesium sulfate and the solvent was evaporated, to give 1.310 g of ethyl 3-[3-([2-(diethoxyphosphoryl)propanoyl]aminomethyl)-4-methoxyphenyl]-2-isopropoxypropionate.
