실험 절차

A mixture of 5 g of 2-butyl-4-chloro-1-[(2'-cyanobiphenyl-4-yl)methyl]-5-(hydroxymethyl)imidazole, 30.2 g of trioctyltin azide (tri-n-octyltin azide), 25 ml of toluene and 1 ml of dimethylformamide was stirred for 24 hours at 115° C. in nitrogen streams. The reaction mixture was, after cooling, concentrated, and there were added 40 ml of ethanol and a solution of 5.2 g of sodium nitrite in 19 ml of water, whose pH was adjusted at 3.4 with conc. hydrochloric acid. The resultant mixture was subjected to extraction with methylene chloride, and the extract was concentrated under reduced pressure. To the concentrate was added hexane, then resulting crystalline precipitates were collected by filtration. The crystals were washed with hexane, then dried to afford 5.27 g (yield 94.7%) of 2-butyl-4-chloro-5-(hydroxymethyl)-1-[[2'-(1H-tetrazol-5-yl)biphenyl-4-yl]methyl]imidazole. The NMR spectrum of the product was in good agreement with that described in J. Med. Chem., 1991, 34, 2525.
