Procedure
A solution of 2.0 g (15.85 mmol) of 4-(3-hydroxypropyl)-1H-imidazole and 5.5 ml (54.3 mmol) of dry ethylamine in 15.6 ml of dimethylformamide is treated with 4.86 g (17.4 mmol) of triphenylmethyl chloride in 5 ml of dimethylformamide under nitrogen. The mixture obtained is stirred at room temperature for 2 hours and is then poured onto 350 g of crushed ice. The resulting solid is collected by filtration, washed three times with water and purified on a chromatographic column using, as eluent, chloroform and then a chloroform/methanol (1/1) mixture to give 1-triphenylmethyl-4-(3-hydroxypropyl)-1H-imidazole, M.p.: 132°-133° C.
