Methyl 2-(3-aminophenoxy)acetate → 3-{[5,6-Bis(4-methoxyphenyl)furo[2,3-d]pyrimidin-4-yl]amino}phenoxyacetic acid methyl ester

Participants

Reaction Steps

Heat 400 mg (1.091 mmol) of 4-chloro-5,6-bis(4-methoxyphenyl)furo[2,3-d]pyrimidine (for preparation see WO 03/018589) and 237.1 mg (1.309 mmol) of 3-aminophenoxyacetic acid methyl ester to 150° C. in an oil bath for 1.5 h. After cooling, add dichloromethane to the residue and purify by means of silica gel (eluent: dichloromethane/ethyl acetate 10:1). 139.3 mg (25% of theory) of the target compound are obtained as a light yellowish solid.
