Downstream synthetic route of 1224724-39-3

The synthetic route of 1224724-39-3 has been constantly updated, and we look forward to future research findings.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.1224724-39-3,Methyl 4-bromo-1H-indole-7-carboxylate,as a common compound, the synthetic route is as follows.

To a solution of methyl 4-bromo-1H-indole-7-carboxylate (6 g, 23 mmol, Preparation 1 step B) in THF (300 mL), water (60 mL) and MeOH (60 mL) was added lithium hydroxide (2.83 g, 118 mmol). Then the mixture was heated to reflux overnight. After cooling to rt, the solvent was removed under reduced pressure, the aqueous layer was acidified by addition of 4 N HC1 to about pH 6. The precipitate was filtered, and the solid was dried to provide 4-bromo-]H-indole-7-carboxylic acid (5.5g, 97%): ?H NMR (DMSO-d6) 3 11.39 (br, 1H), 7.65-7.63 (d, J= 8.0 Hz, 1H), 7.46-7.44 (m, 1H), 7.33-7.31 (d, J= 8.0 Hz, 1H), 6.49-6.48 (m, 1H)., 1224724-39-3

The synthetic route of 1224724-39-3 has been constantly updated, and we look forward to future research findings.

Some tips on 1224724-39-3

1224724-39-3, As the paragraph descriping shows that 1224724-39-3 is playing an increasingly important role.

1224724-39-3, Methyl 4-bromo-1H-indole-7-carboxylate is a indole-building-block compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

To a mixed solution of compound 267c (800 mg, 3.149 mmol) in methanol (6 mL) and tetrahydrofuran (6 mL) was added a solution of lithium hydroxide in water (12 mL) at room temperature. The mixture was stirred at room temperature for 2.5 hours. The reaction solution was concentrated under reduced pressure, water was added to the residue and neutralized with dilute hydrochloric acid, and then extracted with ethyl acetate (80 mL ¡Á 3).The organic phases were combined, washed with saturated brine, and dried over anhydrous sodium sulfate. The filtrate was concentrated under reduced pressure, ethyl acetate and petroleum ether were added to the residue, and the white solid compound 267d, 4-bromo-1H-indole-7-carboxylic acid (360 mg, 44.8% yield) was collected by filtration.
