Reaction Steps

To a stirred solution of 1-(2-tert-butylphenyl)piperazine dihydrochloride (0.125 g, 0.43 mmol) and diisopropylethylamine (0.171 g, 1.32 mmol) in methylene chloride (5.0 mL) at 0° C. was added 4-fluorobenzoyl chloride (0.080 g, 0.51 mmol) and the reaction mixture was warmed to room temperature. After 2 h the reaction mixture was concentrated under reduced pressure and the residue purified by flash column chromatography (silica gel, 100:0 to 95:5 dichloromethane/methanol) to provided (4-(2-tert-butylphenyl)piperazin-1-yl)(4-fluorophenyl)methanone (0.044 g, 30%) as a white solid, mp 137-139° C.
