Compounds 6-13 were prepared starting from 1-(triphenlymethy1)-protected 1H-imidazoles 14 and 15 in several steps. Lithiation with BuLi in T H F followed by reaction with (triphcny1methoxy)acetaldehyde (16) afforded 17 and 18, respectively. 0-Methylation of 17 and 18 gave diethers 19 and 20, respect
