Diisopropylethylamine → HCID 44540317, 화합물

To a solution of 5-bromo-2-pyridinecarboxylic acid (980 mg, 4.83 mmol, available from Alfa Aesar) in DMF (15 ml) was added HATU (1840 mg, 4.83 mmol) and DIPEA (2.53 ml, 14.50 mmol). The mixture was stirred at room temperature for 30 mins then 6-(1H-indol-4-yl)-1H-indazol-4-amine (600 mg, 2.41 mmol) was added and the mixture stirred at room temperature overnight. The reaction mixture was concentrated in vacuo to approx. 5 ml volume and was applied to 2×50 g aminopropyl cartridges that had been pre-conditioned with MeOH. The reaction mixture remained on the cartridges for 2 h before being eluted with MeOH. The eluent was concentrated in vacuo and a precipitate formed, which was collected by filtration to give the title compound (430 mg) as a yellow solid.
