Procedure

A mixture of 186g of boric acid and 990g of benzyl alcohol was heated at 70° C. During the reaction 180ml of a water/benzyl alcohol azeotrope were distilled over. The residue was distilled under a pressure of 0.5-10mm Hg and in this manner 950g of the title compound were obtained as a clear liquid.
