실험 절차

A sample of this product was hydrolyzed using methanol and 3N NaOH. After 2 h at 25° C., the mixture was acidified and extracted with ethyl acetate. After drying-concentration of the extracts, crude travoprost acid was obtained. The crude travoprost acid was esterified using K2CO3 and 2-iodopropane in DMF. After 2 h at 60° C., water and ethyl acetate were added and phase separated, the aqueous layer was extracted with ethyl acetate. After drying-concentration of the extracts, crude travoprost was obtained. UPLC (ACQUITY UPLC HSS C18) analysis of the crude product showed that 2.6% 5,6-trans isomer and some other isomers were found.
