To a cold suspension of 33 g (0.82 mol) 50% sodium hydride in 500 mL dimethylformamide, add 50.4 g (0.315 mol) 4-(1H-imidazol-1-yl)phenol portionwise, maintaining the temp below 10° C. After addition, stir at room temp for 1 hr. Add 93.2 (0.315 mol) 2-chloro-N,N-dibenzylethanamine hydrochloride portionwise followed by 2.35 g (0.16 mol) sodium iodide. Heat the reaction to 50° C. for 24 hr. After this time, quench with 15 mL H2O, filter, and remove the solvents. Dissolve the residue in methanolic HCl and remove the solvents to provide the title compound which can be recrystallized from isopropanol.
