A process for the preparation of solifenacin wherein all the reaction steps, starting from (i) release of (S) -I -phenyl- 1, 2,3, 4 - tetrahydroisoquinoline from its diastereoisomeric salt with D- (-) - tartaric acid, (ii) conversion of (S) - 1 -phenyl - 1, 2, 3, 4 - tetrahydroisoquinoline into 1 - (5) -phenyl - 1, 2, 3, 4 - tetrahydroisoquinolinecarbonyl chloride in the reaction with triphosgene in the presence of pyridine to (iii) the reaction between 1- (5) -phenyl - 1, 2, 3, 4 - tetrahydroisoquinolinecarbonyl chloride and 3- (S) - quinuclidinol in the presence of sodium hydride are carried out without the isolation of intermediates in solid form and the solvents used for the reactions are aprotic solvent. Resulting solifenacin in the free base form is converted into the corresponding succinic acid salt using methods known in the art.
