144690-92-6, The molecularity is the number of molecules that collide during that step in the mechanism. If only a single reactant molecule in an elementary reaction, that step is designated as unimolecular; if there are two reactant molecules, it is bimolecular.144690-92-6. A new synthetic method of this compound is introduced below.
Trityl olmesartan medoxomil (8 g, 10 mmol) is dissolved in THF (50 ml) and 48 % aqueous hydrobromic acid (3.5 ml, 30 mmol) is added. The mixture is stirred for 1 hour at room temperature and then 1 hour at 0 C. The precipitate is filtered, washed with cold THF (20 ml) and dried overnight in vacuum at room temperature to give 5.7 g of olmesartan medoxomil hydrobromide Form B (98.6 % area)
There are, however, a few established termolecular elementary reactions. The reaction of nitric oxide with oxygen appears to involve termolecular steps.
