Embodiment 2
[0227] Example 2 6-(1-acryloylpiperidin-3-ylamino)-7-fluoro-4-(4-(2-methoxyethoxy)phenylamino)-1H-pyrrolo[3, 4-c] Preparation of pyridin-3(2H)-one (G-2)
[0228]
[0229] Step 1: Add compound 2.1 (600mg, 3mmol) and DIPEA (780mg, 6mmol) to a solution of compound 1a (740mg, 2mmol) in NMP (10mL), and react the mixture with microwave at 180°C for 30min under argon atmosphere. LC-MS tracked until the reaction was complete. The reaction solution was cooled to room temperature, diluted with DCM, washed with water and saturated brine respectively, the organic layer was dried, concentrated and purified by combiflash to obtain 300 mg of compound 2-1. MS m / z(ESI):535[M+H] + .
[0230] Step 2: Compound 2-1 (250mg, 0.5mmol), Compound 2.2 (102mg, 0.6mmol), Pd 2 (dba) 3 (45mg, 0.05mmol), Xantphos (54mg, 0.1mmol), and cesium carbonate (326mg, 1mmol) in 1,4-dioxane (15mL) were microwaved at 160°C for 50min under an argon atmosphere. LC-MS tracked until the reaction was complete. The ...
Embodiment 3
[0233] Example 3 6-(1-acryloylazepan-3-ylamino)-7-fluoro-4-(4-(2-methoxyethoxy)phenylamino)-1H-pyrrolo Preparation of [3,4-c]pyridin-3(2H)-one (G-3)
[0234]
[0235] Step 1: The preparation method is the same as that of compound 2-1, except that compound 2.1 in the preparation method of compound 2-1 is replaced by compound 3.1. MS m / z(ESI):549.3[M+H] + .
[0236] Step 2: The preparation method is the same as that of compound 2-2, except that compound 2-1 in the preparation method of compound 2-2 is replaced by compound 3-1. MS m / z(ESI):680.5[M+H] + .
[0237] Step 3: To a solution of compound 3-2 (83 mg, 0.001 mmol) in DCM (5 mL) was added TFA (2 mL). The mixture was stirred at room temperature for 1 h. LC-MS tracked until the reaction was complete. Remove most of TFA under reduced pressure, add saturated sodium bicarbonate solution, adjust pH to 7-8, extract with DCM, combine organic layers, dry and concentrate to obtain compound 3-3, which is directly used in the ...
Embodiment 7
[0240] Example 7 6-(1-acryloylpiperidin-3-ylamino)-7-fluoro-4-(1-methyl-1H-pyrazol-4-yl)-1H-pyrrolo[3,4- c] Preparation of pyridin-3(2H)-one (G-7)
[0241]
[0242] Step 1: Compound 2-1 (150mg, 0.3mmol), Compound 7.1 (150mg, 0.5mmol), Pd(dppf)Cl 2(25mg, 0.03mmol), a mixture of potassium carbonate (130mg, 0.9mmol) in 1,4-dioxane (10mL) and water (1mL) was microwaved at 130°C for 30min under an argon atmosphere. LC-MS tracked until the reaction was complete. The solvent was evaporated to dryness under reduced pressure, and the residue was purified by combiflash to obtain 140 mg of compound 7-1. MS m / z(ESI):581[M+H] + .
[0243] Step 2: A solution of compound 7-1 (140 mg, 0.2 mmol) in TFA (3 mL) was stirred at 80° C. for 3 h. LC-MS tracked until the reaction was complete. The reaction solution was added with saturated sodium carbonate solution to adjust the pH to 7, extracted with DCM, washed with saturated brine, and the organic layer was dried and concentrated to obtai...
