Phenyl isocyanate → N-{4-[1-Ethyl-4-(1H-pyrrolo[2,3-b]pyridin-4-yl)-1H-pyrazol-3-yl]phenyl}-N'-phenylurea

Participants

Reaction Steps

A solution of 4-[1-ethyl-4-(1H-pyrrolo[2,3-b]pyridin-4-yl)-1H-pyrazol-3-yl]aniline (2.2 mmol) in pyridine (4 mL) was treated with phenyl isocyanate (2.4 mmol) and stirred for 1 h at room temperature. The reaction mixture was concentrated in vacuo and purification of the residue by flash chromatography (80-100% ethyl acetate/hexanes) provided the title product as a white powder (50%).
