1914-02-9, name is 3,3-Dimethylindoline, belongs to indolines-derivatives compound, is considered to be a conventional heterocyclic compound, which is widely used in drug synthesis. The chemical synthesis route is as follows. SDS of cas: 1914-02-9
Example 18b Synthesis of 2-[2-(3,3-dimethyl-2,3-dihydroindol-1-yl)-2-oxoethyl]-6-morpholin(D4)-4-yl-3H-pyrimidin-4-one Step 1b: Synthesis of 2-(4-chloro-6-methoxypyrimidin-2-yl)-1-(3,3-dimethyl-2,3-dihydroindol-1-yl)ethanone 0.5 g of the sodium salt of (4-methoxy-6-chloropyrimidin-2-yl)acetic acid (example 8b, step 3b), 0.33 g of 3,3-dimethyl-2,3-dihydro-1H-indole (CAS 1914-02-9), 0.4 ml of pyridine and 5 ml of dimethylformamide are placed in a three-necked flask so as to obtain a homogeneous brown solution. 512 mg of N-[3-(dimethylamino)propyl]-N?-ethylcarbodiimide are added at ambient temperature and the mixture is stirred at ambient temperature for 20 hours. The resulting product is concentrated in a rotary evaporator under vacuum, 40 ml of water are added, extraction is carried out with 3 times approximately 25 ml of dichloromethane, washing is carried out with 50 ml of saturated NaCl solution, drying is carried out over MgSO4, and the resulting product is filtered through a VF filter. The compound obtained is purified by chromatography on silica gel (40-63 mum), elution being carried out with a 98/2 dichloromethane/methanol mixture. The fractions containing the expected compound are combined and evaporated under reduced pressure. 2-(4-Chloro-6-methoxypyrimidin-2-yl)-1-(3,3-dimethyl-2,3-dihydroindol-1-yl)ethanone is isolated: 0.3 g of a yellow oil; yield 41%, which is used as it is in the next step.
The synthetic route of 1914-02-9 has been constantly updated, and we look forward to future research findings.
