Diisopropylethylamine → HCID 44540691, 화합물

3-(Methyloxy)-2-pyridinecarboxylic acid (available from Milestone Pharm Tech, 123 mg, 0.81 mmol), O-(7-azabenzotriazol-1-yl)-1,1,3,3-tetramethyluronium hexafluorophosphate (306 mg, 0.81 mmol) and DIPEA (0.422 ml) were stirred in DMF (2 ml) for 30 mins under nitrogen. Then 6-(1H-indol-4-yl)-1H-indazol-4-amine (100 mg, 0.40 mmol) was added and the reaction was stirred overnight. The reaction was loaded onto an aminopropyl column and left for 3 h, before eluting with 10% MeOH in DCM. Appropriate fractions were combined and evaporated under vacuum. The residue was purified by Mass Directed Automated Preparative HPLC (Method B). The solvent was dried under a stream of nitrogen to give the title compound (49 mg).
