2-(2-甲基-1H-吲哚-3-基)-2-氧代乙酰基 氯化物

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: A solution of 2-methylindole (32.8) in diethyl ether (300 ml.) was added at 30° to oxalyl chloride (35.0g.) diluted with diethyl ether (200 ml.). After stirring for 1 hour the precipitate of 2-methylindolylglyoxylyl chloride was collected by filtration and treated with methanol (300 ml.) to give the methyl ester of 2-methylindol-3-ylglyoxylic acid (30.0 g.) as a red powder m.p. 180°-183°. was collected by filtration treated with methanol (300 ml.)
