Reaktionsschritte

To a solution of 4-[(4-amino-1H-indol-1-yl)methyl]-1-(t-butyloxycarbonyl)-1H-pyrrolo[2,3-b]pyridine (450 mg) in DCM was added 5-chloro-2-methoxyphenyl isocyanate (Int-4, 275 mg, 1.5 mmol). The mixture was stirred overnight, then concentrated, and purified by flash column chromatography to give the desired product 1-(2-methoxyl-5-chlorophenyl)-3-{1-[1-(t-butyloxycarbonyl)-1H-pyrrolo[2, 3-1)]pyridin-4-ylmethyl]-1H-indol-4-yl}urea (540 mg, 80% for two steps).
