Reaction Steps

A suspension of 14.70 g of 4-(4-benzyloxyphenyl)-1-(1-phenylethyl)-1,2,3,4-tetrahydro-pyridin-3-ol [257928-45-3] in 250 ml of dichloromethane is mixed with 6.80 ml of 2,6-lutidine and cooled to 0° C. 12.60 ml of triisopropysilyl trifluoromethanesulphonate are added dropwise, and the reaction mixture is stirred at 0° C. for 1 hour. The reaction solution is poured into 400 ml of water, and the phases are separated. The aqueous phase is back-extracted with 200 ml of dichloromethane, and the combined organic phases are dried with sodium sulphate and evaporated. The title compound is obtained as a yellow-brown oil from the residue by flash chromatography (SiO2 F60). Rf (EtOAc/heptane 1:2)=0.66; Rt=5.83.
