Process for the preparation of tetrazolyl compounds |
| abstract |
The invention provides a method for preparing candesartan cilexetil and related tetrazolyl compounds. More particularly, the invention relates to the preparation of candesartan cilexetil and related tetrazolyl compounds and includes a method of removing a protective group (e.g., triphenylmethane (trityl) protecting group) from an N-protected tetrazolyl compound using a Lewis acid in an inert solvent and in the presence of an alcohol (e.g., reacting an N-protected tetrazolyl compound with ZnCl 2 in the presence of an alcohol). |
