3-{[6-(4-Bromophenyl)-5-(4-fluorophenyl)furo[2,3-d]pyrimidin-4-yl]amino}phenoxyacetic acid methyl ester → 3-{[5-(4-Fluorophenyl)-6-phenylfuro[2,3-d]pyrimidin-4-yl]amino}phenoxyacetic acid methyl ester

Participants

Reaction Steps

Dissolve 115 mg (0.21 mmol) of 3-{[6-(4-bromophenyl)-5-(4-fluorophenyl)furo[2,3-d]pyrimidin-4-yl]amino}phenoxy acetic acid methyl ester in 5 ml of dichloromethane and 5 ml of ethyl acetate, and add 22 mg of 10% palladium on activated carbon under argon. Stir the mixture under a hydrogen atmosphere of 3 bar gauge at RT until the starting material has been converted completely. Filter off the catalyst, concentrate the resulting filtrate under reduced pressure and chromatograph the residue on silica gel (eluent: dichloromethane/ethyl acetate 10:1). 27.9 mg (28.3% of theory) of the target compound are obtained as a colourless solid.
