Abstract
PURPOSE: p-Tosylate salt of mixed acid anhydride of 6-guanidinocaproic acid with p-tosylic acid is made to reat with p-hydroxybenzoic ethyl ester to produce the titled compound used as an intermediate of gabexate mesylate under mild reaction conditions in high yield.
CONSTITUTION: p-Tosylate salt of acid nhydride between 6-guanidinocaproic acid and p-tosylic acid of formula 2 is made to react with p-hydroxybenzoic ethyl ester of formula 3 usually at room temperature to 50°C for about 1 hour to give the objective compound of formulaI. The amount of p-hydroxybenzoic ethyl ester used is equal to or more than the p-tosylate salt in molar quantities.
