Versuchsvorschrift

9 g 4-bromo-N-cyclohexylaniline (VII) (CA registration number [113388-04-8], see Synthetic Communications, 1986, 16(13): 1641-1645 for its preparation) was placed into a four-necked flask and 15 ml (1.5 mol/L) n-BuLi solution in n-hexane. The mixture was stirred for 30 min at room temperature. Then 8 g trimethylsilyl chloride (Me3SiCl) was added and the mixture was stirred for 1 hour. Solvent and excessive Me3SiCl was evaporated under reduced to yield 4-bromo-N-cyclohexyl-N-trimethylsilylaniline) (VIII) which was formulated into a solution with 7.5 ml anhydrous tetrahydrofuran for further use.
