実験手順

A mixture of 5-(3-aminopyrrolidin-1-yl)-N-(3,4-dimethoxyphenyl)thiazolo[5,4-d]pyrimidin-7-amine hydrochloride (100 mg, 0.245 mmol), 1H-indazole-6-carboxylic acid (40 mg, 0.245 mmol), EDCI (97 mg, 0.49 mmol) and N-methylimidazole (60 mg, 0.735 mmol) in 10 mL of DCM was stirred at room temperature for 16 hours. The mixture was washed with water (5 mL), The organic layer was dried over Na2SO4. After filtration and concentration, the residue was purified by preparative HPLC (Gemini 5u C18 150×21.2 mm; inject volume: 3 ml/inj, flow rate: 20 ml/min; wavelength: 214 nm and 254 nm; the gradient conditions are: 25% acetonitrile/75% water (0.1% TFA V/V) initially, and then proceed to 50% acetonitrile/50% water (0.1% TFA V/V) in a linear fashion after just 9 min.) to give N-(1-(7-(3,4-dimethoxyphenylamino)thiazolo[5,4-d]pyrimidin-5-yl)pyrrolidin-3-yl)-1H-indazole-6-carboxamide (45 mg, 36%) as white solid. 1H NMR (300 MHz, DMSO): δ 9.69 (s, 1H), 8.84 (s, 1H), 8.74 (d, 1H, J=6.3 Hz), 8.14 (s, 1H), 8.06 (s, 1H), 7.89 (s, 1H), 7.81 (d, 1H, J=8.4 Hz), 7.63-7.44 (m, 2H), 6.92 (d, 1H, J=9.0 Hz), 4.62-4.25 (m, 2H), 3.96-3.66 (m, 10H), 2.35-2.11 (m, 3H). LC-MS: 516.9 [M+H]+, tR=1.38 min. HPLC: 100% at 214 nm, 100% at 254 nm, tR=5.76 min.
