실험 절차

1-Tert-butyldimethylsilyloxy-2-hydroxy-2-(4-tert-butylphenyl) ethane (0.5 g, 1.622 mmol) is dissolved in dichloromethane and to it is added dihydropyran (0.163 g,1.94 mmol) and toluenesulfonic acid (33 mg, 0.194 mmol). The reaction is stirred for 2 hours after which the mixture is washed with water and dried. The crude residue obtained after concentration is purified by flash chromatography (silica gel; ethyl acetate/hexanes) to obtain the product.
