実験手順

3-(2,6-Difluorophenyl)-1-(4-methylphenyl)-1H-indazole-6-carboxylic acid (30.0 mg, 0.040 mmol, with 6 equivalents of sodium chloride), (1R)-1-(3-methyl-1,2,4-oxadiazol-5-yl)ethanamine bis-hydrochloride (12.5 mg, 0.062 mmol), 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (16.2 mg, 0.085 mmol), 1-hydroxy-7-azabenzotriazole (3.4 mg, 0.025 mmol), and N-methylmorpholine (20 μl, 0.182 mmol) were dissolved in N,N-dimethylformamide (500 μl) at 25° C. The reaction mixture was heated to 50° C. and allowed to stir for 30 min. The reaction was stopped and quenched by addition of water (ca 0.1 mL) and trifluoroacetic acid (ca 0.1 mL). The crude reaction mixture was purified directly by preparative HPLC (Reverse phase (C-18)), eluting with acetonitrile/water+0.1% trifluoroacetic acid (5-95%), to afford the title compound (16.3 mg, 0.023 mmol, 58.2% yield) as a white solid. HRMS [M+1]=474.1739. 1H NMR (400 MHz, CDCl3): δ 8.29 (s, 1H); 7.77 (d, J=8.6 Hz, 1H); 7.66 (d, J=8.2 Hz, 2H); 7.61 (dd, J=8.5, 1.4 Hz, 1H); 7.48-7.40 (m, 1H); 7.38 (d, J=8.1 Hz, 2H); 7.10 (m, 2H); 6.79 (d, J=7.7 Hz, 1H); 5.62 (m, 1H); 2.46 (s, 3H); 2.41 (s, 3H); 1.73 (d, J=7.1 Hz, 3H).
