実験手順

To a stirred solution of 2,2-dimethyl-3-phenyl-3-(3-phenyl-1H-indazol-6-yl)propanoic acid (26 mg, 0.07 mmol), 2-aminothiazole (28 mg, 0.28 mmol), and diisopropylethylamine (0.05 mL) in anhydrous DMF (0.2 mL) was added HATU (106 mg, 0.28 mmol) under argon. After stirring at rt for 2.5 hr and 80° C. for 1 hr, the mixture was concentrated. Purification using reverse phase HPLC (YMC S5 20×100 mm, 10 min. run, solvent A: 10% MeOH: 90% H2O: 0.1% TFA, solvent B: 90% MeOH, 10% H2O, 0.1% TFA) gave 2,2-dimethyl-3-phenyl-3-(3-phenyl-1H-indazol-6-yl)-N-(thiazol-2-yl)propanamide (Example 112, 9 mg, 0.02 mmol, 28% yield) as a solid. MS found: (M+H)+=453. 1H-NMR (500 MHz, CDCl3) δ ppm 7.96 (1H, d, J=8.25 Hz) 7.86 (2H, d, J=8.25 Hz) 7.50 (1H, d, J=8.25 Hz) 7.46 (2H, d, J=8.25 Hz) 7.39-7.43 (2H, m) 7.35 (2H, d, J=7.70 Hz) 7.17-7.26 (4 H, m), 6.96 (1H, d, J=3.30 Hz) 4.62 (1H, s) 1.45 (6H, d, J=3.85 Hz).
