Procedure
Dess-Martin periodinane (0.38 g) was added to a solution of 2-(4-(2-(tert-butyldimethylsilyloxy)ethyl)phenyl)ethanol (example 5, step b) (0.21 g) in dichloromethane (5 mL) and the resulting mixture stirred for 30 min. A mixture of saturated sodium thiosulphate solution (5 mL), saturated sodium bicarbonate solution (5 mL) and ethyl acetate (25 mL) were added and the resulting mixture stirred for 10 min. The organic phase was separated and washed with saturated sodium bicarbonate solution (2×10 mL) and brine (10 mL), then dried over sodium sulphate, filtered and evaporated to give the subtitled compound as a clear oil which was used immediately. Yield 0.20 g.
