실험 절차

(3-Methyl-1H-pyrazol-1-yl)acetic acid (38 mg, 0.27 mmol) (from Art-Chem GmbH), HATU (126 mg, 0.33 mmol) and DIPEA (0.158 ml, 0.91 mmol) were dissolved in DMF (2 ml) and stirred under nitrogen for 30 mins. 6-(1H-Indol-4-yl)-1-(tetrahydro-2H-pyran-2-yl)-1H-indazol-4-amine (100 mg, 0.30 mmol) was added and the reaction was stirred for 5 h. Further (3-methyl-1H-pyrazol-1-yl)acetic acid (38 mg, 0.27 mmol), HATU (126 mg, 0.33 mmol) and DIPEA (0.158 ml, 0.91 mmol) in DMF (1 ml) was added, after stirring together for 10 mins, and the reaction was stirred for 2 days under a nitrogen atmosphere at RT. The reaction was loaded on to a PS-aminopropyl cartridge (10 g) and eluted with DCM. Appropriate fractions were combined and evaporated in vacuo. MeOH (2 ml) and 2 M HCl (aq) (45 μl, 0.09 mmol) were added and stirred for ˜30 mins at RT. The solvent was evaporated in vacuo and the residue was dissolved in MeOH:DMSO (2 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 to give title compound (31 mg).
