| abstract | process for the preparation of crystalline 3,6,9-triaza-3,6,9-tris (carboxymethyl) -4- (4-ethoxybenzyl) undecanoic diacid and the use for the production of primovist <32>. The invention relates to a process for the preparation of crystalline 3,6,9-triaza-3,6,9-tris (carboxymethyl) -4- (ethoxybenzyl) -undecanoic diacid of formula (1) by ester saponification 3,6,9-triaza 3,6,9-tris (tert-butoxycarbonyl) -4- (4-ethoxybenzyl) -undecanoic diacidic di-tert-butyl of formula (11) in an aqueous alkali metal hydroxide solution and the use of 3,6,9-triaza-3,6,9-tris (carboxymethyl) -4 (ethoxybenzyl) -undecanoic diacid of the formula 1 for the production of the 3,6,9-triaza-diacid gadolinium complex 3,6,9-tris (carboxymethyl) -4- (4-ethoxybenzyl) -undecanoic [(gd-eob-dtpa) = primovist <32>]. |
