実験手順
A suspension of ethyl imidazole-4-carboxylate (1.4 g), triethylamine (1.2 g) and chloroform (20 ml) was stirred at room temperature while trityl chloride (3.06 g) was added, and the mixture was stirred at room temperature for 1 h. The resulting solution was washed with water, dried and evaporated to dryness under reduced pressure, and the residue was crystallised from a mixture of ethyl acetate and cyclohexane, to give ethyl 1-tritylimidazole-4-carboxylate, mp 163°-164°.
