Embodiment 1
[0031] Embodiment 1: the preparation of compound 22-23
[0032]
[0033] Compound 2,3-dihydro-1H-indan-2-amine hydrochloride (V, 0.012mol), triethylamine (0.035mol), di-tert-butyl dicarbonate (0.013mol) were dissolved in dichloromethane (50mL), stirred at room temperature for 3h, after the reaction was complete, added water (20mL×2) to wash, washed once with saturated brine, anhydrous MgSO 4 Dry, filter, and concentrate to give a white solid intermediate;
[0034] In the reaction flask, first add LiAlH 4 (0.024mol), under nitrogen protection, slowly add anhydrous tetrahydrofuran (25mL) under ice bath, then dissolve the white solid intermediate in anhydrous tetrahydrofuran (35mL), and slowly drop into the reaction flask under ice bath ;
[0035] After dropping, heat to reflux, after the reaction is complete, cool to room temperature, pour the reaction solution into 10% aqueous sodium hydroxide solution (120mL), then extract with dichloromethane (60mL×3), wash once with sa...
Embodiment 2
[0041] Embodiment 2: the preparation of compound 1-5
[0042]
[0043] In a three-necked reaction flask, add 3-(4-chlorophenyl)glutaric acid (4.1mmol) and Ac 2 O (20mL), stirred, heated to 100°C, reacted for 2h, then concentrated to dryness to obtain an oil. Anhydrous tetrahydrofuran (20 mL), triethylamine (10.3 mmol) and 2-aminoindane hydrochloride (4.1 mmol) were added to the above oil, and stirred overnight at room temperature. After the reaction was complete, it was concentrated to dryness, added water (60 mL), extracted with ethyl acetate (30 mL×3), washed once with saturated brine, dried over anhydrous magnesium sulfate, filtered, and concentrated to dryness to obtain an oil. To the above oil, dichloromethane (30 mL), 2-(7-azabenzotriazole)-N,N,N',N'-tetramethyluronium hexafluorophosphate (HATU, 4.9 mmol), N,N-diisopropylethylamine (DIPEA, 8.2mmol) and 1-(2-aminoethyl)piperidine (4.9mmol), stirred overnight at room temperature. After the reaction is complete, adjus...
Embodiment 3
[0053] Embodiment 3: the preparation of compound 6-9
[0054]
[0055] In a three-necked reaction flask, add 3-phenylglutaric acid (4.8mmol) and Ac 2 O (20mL), stirred, heated to 100°C, reacted for 2h, concentrated to dryness to obtain an oil. Anhydrous tetrahydrofuran (20 mL), triethylamine (12.0 mmol) and 2-aminoindane hydrochloride (4.8 mmol) were added to the above oil, and stirred overnight at room temperature. After the reaction was complete, the reaction solution was concentrated to dryness, poured into water (60 mL), extracted with ethyl acetate (30 mL×3), washed once with saturated brine, dried over anhydrous magnesium sulfate, filtered, and concentrated to dryness to obtain an oil. To the above oil, dichloromethane (30 mL), 2-(7-azabenzotriazole)-N,N,N',N'-tetramethyluronium hexafluorophosphate (HATU, 5.8 mmol), N,N-diisopropylethylamine (DIPEA, 9.6mmol) and 1-(2-aminoethyl)piperidine (5.8mmol), stirred overnight at room temperature. After the reaction is compl...
