Versuchsvorschrift
In analogy to GP 5, 200 mg of 4-methyl-3-(1-methyl-1H-pyrazolo[3,4-c]pyridin-4-ylethynyl)-phenylamine (Intermediate 3.2, 0.4 mmol, 1 eq.) were treated with 47 μL phenyl isocyanate (0.44 mmol, 1.1 eq.) in 4 mL DCM at rt. Aqueous work-up followed by HPLC purification provided the target compound.
