実験手順: To a solution of (4-methanesulfonyl-phenyl)-methanesulfonyl chloride from Step 2 (1.0 g, 3.7 mmol) in CH2Cl2 (40 mL) was added dimethylamine (0.42 g, 9.3 mmol) dropwise. After 18 h, the resulting reaction mixture was diluted with a saturated ammonium chloride solution and ethyl acetate. The organic extracts were washed (HCl 10%, NaHCO3, brine), dried (MgSO4), filtered, and concentrated to provided the C-(4-methanesulfonyl-phenyl)-N,N-dimethyl-methanesulfonamide compound. the resulting reaction mixture The organic extracts were washed (HCl 10%, NaHCO3, brine) dried (MgSO4) filtered concentrated

実験手順: 4-Methanesulfonyl-phenylmethanesulfonyl chloride (10.7 g, 40 mmol) in 100 ml dry tetrahydrofuran was added to a solution of ethynylcyclohexylamine (4.93 g, 40 mmol) and triethylamine (6.13 ml, 44 mmol) in dry tetrahydrofuran (100 ml) at 0-5° C. Then the mixture was stirred for 1 hour at room temperature, poured into 0.05 N hydrochloric acid and stirred again. The precipitate was filtered off, washed with water and dried to yield N-(1-ethynylcyclohexyl)-4-methanesulfonyl-phenylmethane sulfonamide (11.7 g, 82%) as a solid. 1H-NMR (CDCl3) δ 7.93 (d, 2 H), 7.65 (d, 2 H), 4.61 (s, 2 H), 4.32 (s, 1 H), 2.75 (s, 1 H), 3.05 (s, 3 H), 2.15 (m, 2 H), 1.63 (m, 7 H), 1.27 (m, 1 H); MS (IS): 354.1 [M−H]−. stirred again The precipitate was filtered off washed with water dried
