Reaction Steps

To a portion of the above but-3-ynyl-(trans-4-methyl-cyclohexyl)-amine hydrochloride (500 mg, 2.48 mmol) dissolved in pyrrolidine (2.5 mL) was added 1-bromo-4-methanesulfonyl-benzene (583 mg, 2.48 mmol) and the solution was degassed by bubbling nitrogen through for 10 min. Tetrakis(triphenylphosphine)palladium(0) (28 mg, 0.025 mmol) was added and the mixture was heated at 50° C. for 16 h before the volatiles were removed by evaporation and the residue purified by HPLC to yield the intermediate [4-(4-methanesulfonyl-phenyl)-but-3-ynyl]-(trans-4-methyl-cyclohexyl)-amine.
