Versuchsvorschrift

A solution of [5-(benzhydrylidene-amino)pyridin-3-yl]-(4-chloro-7-methyl-7H-pyrrolo[2,3-d]pyrimidin-5-yl)-methanone (Preparation 229, 30 g, 0.066 mol) in THF (200 mL) was added aq. citric acid (200 mL), the mixture was stirred for 30 min at room temperature. Ether was added and the layers were separated. The aqueous layer was adjusted to pH7 by aqueous Na2CO3. Then the mixture was filtered. The filter cake was evaporated with toluene and the residue was washed with EtOAc (200 mL) to give the title compound as a brown solid in 95% yield, 18 g.
