The organic phase was sequentially washed with a diluted solution of sodium hypochlorite (2 x 5 mL) and brine (2 x 5 mL), dried over magnesium sulphate, filtrated and evaporated. The residue was purified by column chromatography on silica gel using a 2:1 hexane:ethyl acetate mixture as eluent, to give 3-(2-methyl-1,3-dioxolan-2-yl)-1-phenylpropan-1-ol (8). Yield: 0.18 g (84%); CAS No: 167644-51-1.
