The present invention relates to processes for preparing 1-butyl-2-[2'-(2H-tetrazol-5-yl)biphenyl-4-ylmethyl]-1H-indole-3-carboxyli c acid and to intermediates useful in such processes. The present invention also relates to a process for deprotecting compounds containing a protected 2H-tetrazolyl group, which process comprises reacting a the protected compound with a Lewis acid in the presence of a thiol.
The present invention is directed to compounds which inhibit farnesyl-protein transferase (FTase) and the farnesylation of the oncogene protein Ras. The invention is further directed to chemotherapeutic compositions containing the compounds of this invention and methods for inhibiting farnesyl-protein transferase and the farnesylation of the oncogene protein Ras.
The invention is concerned with novel N-(4-carbamimidoyl-phenyl)-glycine derivatives of the formula:
