A mixture of 227 mg of rac-(1R*,2R*,4R*)-2-(2-hydroxy-ethyl)-5-phenyl-bicyclo[2.2.2]oct-5-en-2-ol, 195 mg of Ts-Cl, 0.16 mL of NEt3 and 11 mg of DMAP in 3 mL toluene was stirred overnight at rt. The reaction mixture was quenched with water, the organic phase was separated, washed with brine and evaporated. The residue was purified by CC with Hept-EtOAc (6:4) to yield 0.32 g of oily rac-toluene-4-sulfonic acid (1R*,2R*,4R*)-2-(2-hydroxy-5-phenyl-bicyclo[2.2.2]oct-5-en-2-yl)-ethyl ester as yellowish oil.
