Embodiment 1
[0203] Example 1: Synthesis of Compound I-1
[0204] The synthetic route is as follows:
[0205]
[0206] The first step: Synthesis of (S)-4-bromo-2-nitro-5-((tetrahydrofuran-3-yl)oxy)benzoic acid methyl ester (B1-2)
[0207]
[0208] Compound B1-1 (5.0 g, 18 mmol) was dissolved in DMF (50 mL), potassium carbonate (3.7 g, 27 mmol) and (S)-3-hydroxytetrahydrofuran (1.74 g, 19.8 mmol) were added, and the reaction was carried out at 80°C. After the reaction was completed, the reaction solution was directly concentrated to obtain the crude product. Water was added to the crude product, extracted three times with dichloromethane, the organic phases were combined, dried over anhydrous sodium sulfate, filtered, and concentrated under reduced pressure to obtain the crude product. The crude product was separated and purified by column chromatography to obtain compound B1-2 (3.73 g, yield 60%).
[0209] The second step: Synthesis of (S)-2-amino-4-bromo-5-((tetrahydrofuran-3-yl)...
Embodiment 2
[0223] Example 2: Synthesis of Compound 1-2
[0224] The synthetic route is as follows:
[0225]
[0226] The first step: the synthesis of (S)-5-(3-acetamidopyrrolidin-1-yl)-4-bromo-2-nitrobenzoic acid methyl ester (B2-2)
[0227]
[0228] Compound B1-1 (2.0 g, 7.22 mmol) was dissolved in DMF (20 mL), potassium carbonate (1.49 g, 10.8 mmol) and (3S)-(-)-3-acetamidotetrahydropyrrole (compound B2-1) were added. ) (1.02g, 7.94mmol), reacted at 80°C for 5h. After the reaction was completed, the reaction solution was directly concentrated to obtain the crude product. Water was added to the crude product, extracted three times with dichloromethane, the organic phases were combined, dried over anhydrous sodium sulfate, filtered, and concentrated under reduced pressure to obtain the crude product. The crude product was separated and purified by column chromatography to obtain compound B2-2 (2.36 g, yield 85%).
[0229] The second step: the synthesis of (S)-5-(3-acetamidopyrrol...
Embodiment 3
[0243] Example 3: Synthesis of Compound 1-3
[0244] The synthetic route is as follows:
[0245]
[0246] The first step: the synthesis of (S)-5-((1-acetylpyrrolidin-3-yl)oxy)-4-bromo-2-nitrobenzoic acid methyl ester (B3-1)
[0247]
[0248] Compound B1-1 (1.6 g, 5.76 mmol) was dissolved in N,N-dimethylformamide (20 mL), potassium carbonate (1.20 g, 8.64 mmol) and 1-[(3S)-3-hydroxypyrrolidine were added -1-yl]Ethan-1-one (0.82 g, 6.34 mmol), reacted at 80°C overnight. After the reaction was completed, the reaction solution was directly concentrated to obtain the crude product. Water was added to the crude product, extracted three times with dichloromethane, the organic phases were combined, dried over anhydrous sodium sulfate, filtered, and concentrated under reduced pressure to obtain crude product B3-1 (1.8 g, yield 81%).
[0249] The second step: the synthesis of (S)-5-((1-acetylpyrrolidin-3-yl)oxy)-2-amino-4-bromobenzoic acid methyl ester (B3-2)
