Procedure

To 79.2 g of the diol from Example 2 in 400 ml of methylene chloride is added 100 ml of tiethylamine, followed by 91 g of tosyl chloride in 200 ml methylene chloride. The reaction mixture is stirred at room temperature overnight. The salts are then filtered off and the mixture washed with water, brine and water. The organic layer is dried (MgSO4), filtered and concentrated to obtain 3-(o-hydroxyphenyl)-1-tosyloxypropane as a light brown oil which is used directly in the next step.
