Synthesis
73-22-3
2899-28-7
Preparation of Example 110 Ethyl L-tryptophan hydrochloride: L-tryptophan (14.3 g, 0.07 mol) was dissolved in 200 ml of ethanol containing about 7 g of anhydrous hydrogen chloride and the reaction was carried out at reflux for 5 hours. After completion of the reaction, the mixture was cooled and the precipitated solid was purified by recrystallization from a solvent mixture of ethanol/ether. The product was obtained as 17.4 g in 92.5% yield, melting point not provided. The product was chemically named L-2-amino-3-indolepropionic acid ethyl ester hydrochloride.
