الإجراء التجريبي

The title compound was prepared by combining 4-iodopyrazole (10 g, 52 mmol), triphenylmethyl chloride (14.4 g, 51.6 mmol), triethylamine (NEt3) (7.2 mL, 52 mmol), and DMF (80 mL). After stirring overnight, the mixture was poured onto ice water. The precipitated solid was collected and recrystallized to give the title compound as a solid, mp 193-194° C.
