PROCESS FOR PREPARATION OF TELMISARTAN

A process for preparation of telmisartan comprises: (i) oxidation of compound of formula (a), wherein R2 is a hydrogen atom or a substituent of formula (b), in which R1 is a protecting group for the carboxyl function, to an aldehyde of formula (c), in which R2 is defined as in the formula (a), and, optionally, (ii) in case R2 in the compound (c) thus obtained is a hydrogen atom, iV-alkylation of the compound (c) with a biphenyl derivative, (iii) treatment of the compound (c) thus obtained with N- methyl- o-nitroaniline in a cyclocondensation reaction, and (iv) cleavage of the protecting group R1.
