Diisopropylethylamine → 2-(5-chloro-1H-pyrrolo[2,3-b]pyridin-3-yl)-5-fluoro-N-((1S,3R)-3-isocyanato-3-methylcyclohexyl)pyrimidin-4-amine

Participants

Reaction Steps

To a solution of (1R,3S)-3-[[2-(5-chloro-1H-pyrrolo[2,3-b]pyridin-3-yl)-5-fluoro-pyrimidin-4-yl]amino]-1-methyl-cyclohexanecarboxylic acid, 826, (0.100 g, 0.216 mmol) and (azido(phenoxy)phosphoryl)oxybenzene (0.093 mL, 0.432 mmol) in 10 mL of toluene was added 1 mL of N-ethyl-N-isopropyl-propan-2-amine. The reaction was warmed to reflux overnight. The mixture was concentrated to dryness and the residue was purified by silica gel chromatography (EtOAc), yielding 40 mg of desired product as a white foam.
