Cancer is one of the most important diseases. It is the second leading cause of death worldwide following cardiovascular disease. There is a need to develop new chemotherapeutic agents for the treatment of cancer and it is still a significant task for med

The invention provides a new process for the preparation of solifenacin or a pharmaceutically acceptable acid addition salt thereof, comprising reacting (R)- quinuclidin-3-yl phenethylcarbamate with benzaldehyde in the presence of an acid to obtain a diasteroisomeric mixture (S,R)-((R)-quinuclidin-3-yl) 1 -phenyl-3,4- dihydroisoquinoline-2(1 H)-carboxylate of formula (IV) which can be resolved and the solifenacin or a pharmaceutically acceptable acid addition salt thereof recovered. The invention also provides the new key intermediate (R)-quinuclidin-3-yl phenethylcarbamate involved in the process. Further the invention provides a method for the transformation of (R)-((R)-quinuclidin-3-yl) 1 -phenyl-3,4- dihydroisoquinoline-2(1 H)-carboxylate into a diasteroisomeric mixture (S,R)-((R)- quinuclidin-3-yl) 1 -phenyl-3,4-dihydroisoquinoline-2(1 H)-carboxylate.

A series of 4-azidobenzylcarbamates [4-N3-C6H4-CH2-O-CO-N(H)-C 6H4-X; X = H, Me, MeO, Br, Cl, NO2] have been prepared in good yield, and in high purity, by reaction of 4-azidobenzyl alcohol with the corresponding aryl isocyanate, or by displacement of 4-nitrophenol from 4-azidobenzyl-4-nitrophenylcarbonate by the appropriate amine. The 4-azidobenzylcarbamates were shown to undergo rapid reduction in the presence of dithiothreitol, and the resultant 4-aminobenzylcarbamates underwent immediate cascade degradation to release the target amine. The mild conditions used in this conversion may prove useful in the protection of amines during synthetic procedures or as a possible mode of bioactivation of prodrugs.
