Reaction Steps

To a solution of 1-(4-bromo-phenyl)-1-methyl-ethylamine (400 mg, 1.84 mmol) in diisopropylethylamine (4 mL) was added N,N-bis(2-chloroethyl)-4-methylbenzene sulphonamide (500 mg, 1.68 mmol) and the reaction subjected to microwave irradiation at 150° C. for 9 h afterwhich time the reaction was concentrated in vacuo and the crude residue purified by reverse phase preparative HPLC-MS to afford 1-[1-(4-bromo-phenyl)-1-methyl-ethyl]-4-(toluene-4-sulfonyl)-piperazine as a peach solid (375 mg, 47%).
