Procedure

72 mg of 1-(4-chloro-benzyl)-5-fluoro-2-phenoxymethyl-6-piperazin-1-yl-1H-benzoimidazole (0.16 mmol) and 0.033 ml TEA (0.24 mmol) were dissolved in 1.5 ml dichloromethane and treated with 0.023 ml benzoylchloride (0.2 mmol). After 1.5 h of stirring at rt, the reaction mixture was diluted with dichloromethane, washed with water, saturated sodium bicarbonate and brine, dried with magnesium sulfate, filtered and concentrated in vacuo, leading to 84 mg residue which was purified by column chromatography (9 g silicagel, ethylacetate/heptane 2:1). 69 mg product as a light yellow solid (98%) was obtained. MS (ISP) 555.3 (M+H)+.
