Reaction Steps

To a suspension of lithium aluminum hydride (21 mg, 0.54 mmol) in THF (2 mL), 1-(4-methylphenyl)piperazine hydrochloride (32 mg, 0.13 mmol) was added. After 10 minutes, a solution of ethyl 2-(2,4-dichlorophenyl)-1-(4-chlorophenyl)-1H-imidazole-4-carboxylate (39 mg, 0.1 mmol) in THF (2 mL) was added dropwise. The reaction mixture was stirred for 10 minutes, and diluted by water. The organic layer was dried over MgSO4, filtered, and concentrated. The residue was purified by HPLC (YMC-packed Pro C18 20×150 mm column, 10-90% CH3CN in H2O/TFA, 25 mL/min) to give the product 1-{[1-(4-chlorophenyl)-2-(2,4-dichlorophenyl)-1H-imidazol-4-yl]methyl}-4-(4-methylphenyl)-piperazine (1.4 mg, 2% yield): LC-MS m/z 511.1 (MH+), retention time 2.94 min (method 1). 1H NMR (300 MHz, CDCl3) δ: 2.29 (3H, s), 3.42-3.49 (8H, br), 4.39 (2H, s), 6.85-7.41 (11H, m), 7.54 (1H, s).
