Reaction Steps
500 mg of 5-(1-ethoxyethyl)-4-methyl-beta-carboline-3-carboxylic acid ethyl ester was refluxed with 5 ml of 1N sodium hydroxide solution and 20 ml of ethanol for 3 hours. Then it was acidified with glacial acetic acid, suctioned off and washed with water. 400 mg of 5-(1-ethoxyethyl)-4-methyl-beta-carboline-3-carboxylic acid was obtained, which after good drying over phosphorus pentoxide in a vacuum was further reacted.
