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

Participants

Reaction Steps

To a solution of 4-methyl-2-(methyloxy)benzoic acid (67 mg, 0.40 mmol) in DMF (1 ml) were added HATU (248 mg, 0.40 mmol) and DIPEA (0.211 mL, 1.21 mmol). The mixture was stirred for 30 mins under nitrogen before addition of 6-(1H-indol-4-yl)-1H-indazol-4-amine (50 mg, 0.201 mmol). The reaction was stirred for 2 h then it was loaded onto PS-aminopropyl cartridge (5 g) 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. Solvent was evaporated under a stream of nitrogen to give title compound (13 mg).
