Trifluoroacetic acid → 7-chloro-3-(3,5-dimethylphenyl)-6-(3-oxo-3-pyrrolidin-1-yl-propyl)-4-(2-piperidin-2-yl-ethoxy)-1H-quinolin-2-one

Participants

Reaction Steps

To a solution of 2-{2-[7-chloro-3-(3,5-dimethylphenyl)-2-oxo-6-(3-oxo-3-pyrrolidin-1-yl-propyl)-1,2-dihydroquinolin-4-yloxy]-ethyl}-piperidine-1-carboxylic acid tert-butyl ester (9.0 mg in 2.0 dry methylene chloride) was added a few drops of anisole followed by 1.0 mL of trifluoroacetic acid and the mixture stirred at room temperature. After 30 minutes the solvents were removed in vacuo and the resulting residue purified by flash chromatography on silica gel (methylene chloride:10% ammonium hydroxide in methanol, 9:1) to give the title compound (7.0 mg). MASS: 536 (M+H)
