Hydrochloric Acid → HCID 9976875, compound

Participants

Reaction Steps

A solution of 2.0 g of methyl p-[2-(p-amidinobenzenesulphonamido)ethyl]phenoxyacetate hydrochloride in 100 ml of ethanol and 50 ml of 1 N sodium hydroxide solution was stirred under argon for 90 minutes. For the working up, dilute hydrochloric acid was used to neutralize to pH 6-7, and the mixture was concentrated in vacuo up to 50° C. The crystals which separated out were filtered off with suction and dried over KOH in vacuo at 50° C. 1.70 g of pure p-[2-(p-amidinobenzenesulphonamido)ethyl]phenoxyacetic acid, melting point 292°-293° C., were thus isolated.
