Versuchsvorschrift

Add 109 mg (0.435 mmol) of boron tribromide at RT to a mixture of 170 mg (0.364 mmol) of 3-{[5-(4-methoxyphenyl)-6-phenylfuro[2,3-d]pyrimidin-4-yl]amino}phenoxyacetic acid and 4.5 ml of dichloromethane. Stir the mixture at RT overnight and then hydrolyse with 1N hydrochloric acid. After adding dichloromethane, filter off the insoluble solid and dry overnight under high vacuum. 128.6 mg of the target compound are obtained, which can be purified further by recrystallization from isopropanol.
