69% | Synthesis of 3-indole glyoxylic acid, methyl ester Commercially available 3-indole glyoxylic acid (9.55 g) was suspended in methylene chloride (300 mL), and cooled on ice. Thereafter, to the suspension was added oxalyl chloride (8.8 mL), followed by stirring at 20C for 20 hrs. The reaction fluid was cooled on ice, and after adding methanol (190 mL) thereto, the reaction fluid was stirred at 25C for 1 hour. To the reaction fluid were added water and methylene chloride, and thus deposited crystals were filtrated, followed by washing of the crystals with methylene chloride. The crystals were dried under a reduced pressure to obtain 3-indole glyoxylic acid, methyl ester (7.07 g, 69%). |

16.1 (1H-indol-3-yl)-oxo-acetic acid A mixture of 610 mg of methyl indolyl-3-glyoxylate and 3.3 cm3 of 1N soda in 3.3 cm3 of water is heated for 1 h at 80 C., then it is cooled on an ice bath and 3.5 cm3 of 1N hydrochloric acid is added. The mixture is extracted with ethyl acetate. The organic phases are combined and dried over sodium sulfate, filtered and concentrated to dryness under reduced pressure (2.7 kPa) to give 554 mg of (1H-indol-3-yl)-oxo-acetic acid in the form of a yellow solid. |
