반응 단계
1.00 g. (2.87 mmoles) of ethyl-5-bromo-tryptamine-2-carboxylate hydrochloride are boiled for 2 hours in a mixture of 10 ml. of ethanol and 10 ml. of 4 n aqueous sodium hydroxide solution. The mixture is cooled with ice, acidified to pH 6 with glacial acetic acid, and the separated crystals are collected by filtration. 0.75 g. (91%) of 5-bromo-tryptamine-2-carboxylic acid are obtained; m.p.: 248°-249° C.
