실험 절차

To a solution of 2-(4-chloro-2-hydroxy-phenoxy)-1-[4-(4-fluoro-benzyl)-(2R)-2-methyl-piperazin-1-yl]-ethanone (0.168 g, 0.427 mmol) in methylene chloride (2 mL) was added triethylamine (0.12 mL, 0.86 mmol). The solution was cooled to −5° C. via an acetone/ice bath then cyanogen bromide was added (0.22 mL, 0.66 mmol). The reaction was stirred at −5° C. for 30 minutes then concentrated in vacuo to give the crude title compound which was taken directly on to the next step (0.17 g).
