Versuchsvorschrift

2-Bromo-4-methylpentanoyl chloride (IV, Example 2) is added dropwise to methyl alcohol (200 ml.) at 0°. After two hours the methanol is removed under reduce pressure and the residual oil is partitioned between chloroform and water. The chloroform is separated from the water and removed under reduced pressure to give a residual oil which is distilled under reduced pressure to give the title compound, b.p. 78°-90°/30 mm.
