PROCESS FOR THE PREPARATION OF TELMISARTAN

The invention relates to processes for preparing telmisartan or a pharmaceutically acceptable salt thereof as well as to a process for preparing a telmisartan cyano intermediate. Moreover, the invention relates to a multilayer pharmaceutical tablet comprising (a) at least one first tablet layer comprising 1 to 50 wt. -% telmisartan or a pharmaceutically acceptable salt thereof by weight of the first tablet layer and (b) at least one second tablet layer comprising 1 to 50 wt.-% of a diuretic and 50 to 99 wt.-% of at least one filler by weight of the second tablet layer, wherein the combined weight of the diuretic and the at least one filler is at least 87 wt.-% by weight of the second tablet layer. The invention also relates to a process for the preparation of a multilayer pharmaceutical tablet.
