Participants

Reaction Steps

To a solution of 33 mg of ethyl 3-[3-(aminomethyl)-4-methoxyphenyl]-2-isopropoxypropanoate and 25 mg of 2,4-dichlorobenzenesulfonyl chloride in 0.8 ml of dichloromethane was added 40 μl of pyridine under ice-cooling, and stirring was continued at room temperature for 4 hours. After removing the solvent, to the residue were added 1.0 ml of ethanol and 0.3 ml of 2N aqueous sodium hydroxide, and the mixture was stirred at room temperature for 2 hours. The reaction solution was diluted with water, and neutralized with 2N hydrochloric acid. The mixture was extracted with ethyl acetate and concentrated. Then, the residue was purified by HPLC using a reverse-phase column by using an elution solvent of water-acetonitrile-trifluoroacetic acid system, to give 2.0 mg of the title compound.
