Procedure

To a solution of 3-[4-chloro-3-(hydroxymethyl)phenyl]propanenitrile from the previous step (1 eq.) in CH2Cl2 (0.1 M) was added Dess-Martin periodinane (1.1 eq.) portionwise. The resulting suspension was stirred at RT for 2 h. The reaction was quenched with MeOH and H2O. The organic layer was separated and the aqueous layer was back-extracted with EtOAc. The combined organic extracts were washed sat. aq. NaHCO3 and brine, dried over Na2SO4 and filtered. Concentration of the filtrate in vacuo afforded the title compound as a pale yellow oil.
