실험 절차

To the solution of 180 g of) 7-(Toluene-4-sulfonyl)-7-aza-bicyclo[4.1.0]heptane and 18 g of Copper(II)acetyl acetonate in 1500 ml of dry THF was added 86 ml of a 10 M solution of methyllithium dropwise over 30 min. The mixture was stirred under nitrogen atmosphere for 8 h. It was then washed with water and extracted with ethyl acetate twice. The combined organic layers were concentrated. The resulting residue was purified by chromatography (silica, hexan/ethyl acetate) to afford 120 g (62%) of 4-Methyl-N-(trans-2-methyl-cyclohexyl)-benzenesulfonamide
