59908-47-3, 5-Chloro-1-methyl-1H-indole-2-carboxylic acid is a indole-building-block compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated,59908-47-3
Production Example 5-4tert-butyl 6-{[5-chloro-1-methyl-1H-indol-2-yl]carbonyl}amino)octahydroisoquinoline-2(1H)-carboxylate To a methanol solution (100 mL) of the compound obtained in Production example 5-3 (3.3 g), 10% palladium carbon (500 mg) was added, and the resulting solution was stirred overnight at room temperature under 1 atm hydrogen atmosphere. The reaction solution was filtered and the filtrate was concentrated under reduced pressure. To a DMF (70 mL) solution of the residue, commercially available 5-chloro-1-methyl-1H-indole-2-carboxylic acid (2.4 g), HATU (4.4 g) and subsequently diisopropylethylamine (4.1 mL) were added, and the resulting solution was stirred overnight at room temperature. Water was added to the reaction solution, and the solution was extracted with ethyl acetate. The organic layer was dried over anhydrous sodium sulfate, and the solvent was distilled off under reduced pressure. The resulting residue was purified by silica gel column chromatography (hexane:ethyl acetate=4:1 to 1:2), whereby the title compound (3.2 g) was obtained as a single optically active isomer (the arrangement in the structural formula is a relative configuration).
As the paragraph descriping shows that 59908-47-3 is playing an increasingly important role.
