1,2-Dimethoxyethane → N-Decyl-3-(3-[4-Methoxycarbonyl-2-oxo-pyrrolidino]phenyl)propenamide

참여 물질

반응 단계

To a stirred mixture of 415 mg. of N-decyl-3-(3-[4-carboxy-2-oxo-pyrrolidino]phenyl)propenamide and 15 ml. of 1,2-dimethoxyethane is added a solution of 1.5 mmoles of diazomethane in 5 ml. of ether. The reaction mixture is stirred at room temperature for 16 hours, and then the excess diazomethane is decomposed by the addition of a few drops of acetic acid. The total solvents are removed by evaporation in vacuo, and the residue is dissolved in ethyl acetate. The ethyl acetate solution is washed with 1 N sodium hydroxide, followed by water, followed by saturated sodium chloride solution, and then dried using sodium sulfate. Evaporation of the dried ethyl acetate solution in vacuo affords the title compound.
