Procedure

Boric acid (1 mole) and 2-methyl-2,4-pentanediol (1 mole) were placed in a reaction vessel with 1000 ml of benzene and the mixture refluxed until 2 moles of water were removed. Evaporation of the benzene at reduced pressure gave a liquid which slowly crystallized to give a white solid mp 73°-75° C [literature mp 69°-70° C, H. Steinberg and D. L. Hunter, Ind. & Eng. Chem 49°, 174°-181 (1957)].
