Preparation of pyrrolidine-1,2-dicarboxanilide derivatives for use as factor Xa inhibiting antithrombotic agents, comprises reacting pyrrolidine-2-carboxylic acid with phenyl isocyanate then aniline derivative

摘要

Preparation of pyrrolidine-1,2-dicarboxylic acid dianilide derivatives (I) involves reacting a pyrrolidine-2-carboxylic acid (II) with a phenyl isocyanate (III) and then reacting the obtained 1-phenylcarbamoyl-pyrrolidine-2-carboxylic acid (IV) with an aniline derivative (V). The intermediates (IV) are new compounds. The preparation of pyrrolidine-1,2-dicarboxylic acid dianilide derivatives of formula (I), or their derivatives, solvates or stereoisomers (including mixtures in all proportions), involves: (a) reacting a pyrrolidine-2-carboxylic acid of formula (II) with an isocyanate of formula (III); and (b) reacting the obtained 1-phenylcarbamoyl compound of formula (IV) with an aniline derivative of formula (V).
