L-Tryptophan, ethyl ester, hydrochloride (1:1) Use and Manufacturing
To the reactor were added L-Tryptophan ethyl ester hydrochloride (1 g, 7 mmol) was dissolved in pyridine solution (30 mL). Add N-methyl isatoic anhydride (1.3 g, 7.3 mmol), the reaction was carried out at room temperature for 12 hours. After the reaction, the reaction solution was evaporated to dryness. The residue was purified by silica gel column chromatography ( petroleum ether: ethyl acetate = 4:1). A yellow solid 710 mg was obtained in a yield of 52%.
