Diisopropylethylamine → N-[6-(1H-Indol-4-yl)-1H-indazol-4-yl]-5-methyl-2-(methyloxy)benzamide

To a solution of 5-methyl-2-(methyloxy)benzoic acid (67 mg, 0.40 mmol) in DMF (1 ml), HATU (248 mg, 0.40 mmol) and DIPEA (156 mg, 1.208 mmol) were added. The reaction was stirred for 30 mins under nitrogen before addition of 6-(1H-indol-4-yl)-1H-indazol-4-amine (50 mg, 0.20 mmol). The reaction was stirred for 3 h then it was loaded onto a PS-aminopropyl cartridge and left for 3 h. The cartridge was washed with 10% MeOH in DCM. Appropriate fractions were combined and the solvent was evaporated. The residue was dissolved in MeOH:DMSO (1 ml; 1:1, v/v) and purified by Mass Directed Automated Preparative HPLC using method B. The solvent was dried under a stream of nitrogen. The residue was dissolved in DMSO and further purified by HPLC using the following conditions:
