Reaction Steps

A solution of 4-(dihydroxyboryl)benzoic acid (1.66 g, 10 mmol) and pinacol (12 mmol) in toluene (70 mL) was refluxed in a Dean-Stark apparatus for 16 hours and concentrated. The concentrate was triturated with diethyl ether and filtered to provide the desired product of sufficient purity for subsequent use.
