A new method for the preparation of solifenacin by reacting quinuclidin-3-ol and bis (aryl) carbonate to form (3R)-l -azabicyclo[2.2.2]oct-3-yl 4-aryl carbonate of formula (IVa); and treating (3R)-I - azabicyclo[2.2.2]oct-3-yl 4-aryl carbonate of formula (IVa) with (1S)- I -phenyl- 1, 2, 3, 4- tetrahydroisoquinoline in an inert atmosphere to form a Solifenacin base which is converted into its pharmaceutically acceptable salts. The invention also provide new compound, (3R)-1 - azabicyclo[2.2.2]oct-3-yl 4-aryl carbonate, which is used as an intermediate for the preparation of Solifenacin base and a process for the preparation thereof.
