Versuchsvorschrift

A solution of 1 l of ethanol and 27 g (0.7 mole) of sodium boranate was added in the course of 2 hours to 412 g (2 moles) of the product from Example 1, at from 25° to 30° C. The ethanol was then stripped off and the residue was acidified with dilute sulfuric acid, washed and then worked up by distillation in the conventional manner. Boiling point: 77° C/0.1 mm Hg; nD25 : 1.4894; yield 82%; the structure was confirmed by the nuclear resonance spectrum.
