الإجراء التجريبي
A suspension of 2-furoamide in 1,2-dichloroethane was treated with oxalyl chloride; 2-furoylisocyanate was isolated by distillation. This product was reacted with the hydroxypropylimidazole, as for the starting material of Example 12, to give 2-fluoro-4-[3-(fur-2-yl)carbamoyloxypropyl]-1-triphenylmethylimidazole, having the following n.m.r. spectrum in d6DMSO: 1.82 (m, 2H); 2.47 (t, 2H); 4.07 (t, 2H); 6.3 (s, 1H); 6.64 (m, 1H); 7.0-7.45 (m, 15H); 7.5 (m, 1H); 7.91 (m, 1H); 10.1 (br, 1H).
