Trifluoroacetic acid → (2R)-3-(2-Fluorophenyl)-N-methyl-2-(methylamino)propionamide

참여 물질

반응 단계

N-((1R)-2-(2-Fluorophenyl)-1-(methylcarbamoyl)ethyl)-N-methylcarbamic acid tert-butylester (2.4 g; 7.73 mmol) was dissolved in methylene chloride. Trifluoroacetic acid (1 0 mL) was added and the reaction mixture was stirred for 30 min at room temperature. Methylene chloride (30 mL), an aqueous solution of sodium hydrogen carbonate/sodium carbonate (pH 9; 30 mL) and sodium hydrogen carbonate (solid) were added to the reaction mixture until pH 8. The organic phase was dried (magnesium sulfate) and evaporated in vacuo to afford 1.1 g of (2R)-3-(2-fluorophenyl)-N-methyl-2-(methylamino)-propionamide.
