实验过程

A solution of 250 mg (0.59 mmol) of trans-N-[4-(5-Chloro-pent-1-ynyl)-cyclohexyl]-N-methyl-4-trifluoromethyl-benzenesulfonamide in 10 ml butan-2-one was treated with 136 mg of NaI (0.91 mmol) and heated at 80° C. for 48 h. Evaporation gave 330 mg of crude trans-N-[4-(5-Iodo-pent-1-ynyl)-cyclohexyl]-N-methyl-4-trifluoromethyl-benzenesulfonamide which was used directly for the next step, MS: 514 (MH+).
