4-Methyl-1H-imidazole (36.53 mmol, 1 eq) of was dissolved in 120 mL of dimethylformamide, triethylamine (73.06 mmol, 2 eq.) and chlorotriphenylmethane (40.1 mmol, 1.1 eq) where added. The mixture was stirred for 3.5 h. The precipitate filtered off and was washed by means of ice-cooled dimethylformamide (2×50 mL) and water (2×50 mL). After removal of the solvent the remaining product was dried over P4O10.
