Reaction Steps

N-[1-(4-bromothiophen-2-yl)-2-{[tert-butyl(dimethyl)silyl]oxy}ethyl]-3-methylbutan-1-amine (248 mg, 0.610 mmol) and DMAP (3.7 mg, 0.031 mmol) were dissolved in 2 mL pyridine and benzenesulfonyl chloride (234 μl, 1.830 mmol) was added. The resulting mixture was heated at 75° C. overnight, after which the mixture was cooled to room temperature, toluene was added and the mixture was concentrated in vacuo. The title compound was purified on silica gel (EtOAc/hexanes).
