Procedure
The reaction and work up was conducted as described in the preparation of compound 163 using 2-bromophenethyl alcohol (5 g, 25 mmol) in pyridine (12 mL) and p-toluenesulfonyl chloride (5.2 g, 27.5 mmol). The crude product was purified by flash chromatography eluting with EtOAc/petroleum ether 1:4. This afforded the title compound as a colourless crystalline compound.
