Versuchsvorschrift
In a similar manner to Example 33, N-[4-(4-amino-7-cyclopentyl-7H-pyrrolo[2,3-d]pyrimidin-5-yl)-2-methoxyphenyl]benzenesulphonamide was reacted with boron tribromide in dichloromethane at -10° C. to give N-[4-(4-amino-7-cyclopentyl-7H-pyrrolo[2,3-d]pyrimidin-5-yl)-2-hydroxyphenyl]benzenesulphonamide, m.p. 265-267° C. The structure was confirmed by 1H nmr and mass spectra.
