A solution of 3-methylbutylmagnesium bromide is prepared by treating 15.1 g. of 3-methylbutyl bromide with 2.7 g. of magnesium turnings in 50 ml. of dry tetrahydrofuran. The resultant Grignard reagent is added dropwise to a solution of 34.5 g. of 1,11-dibromoundecane and 0.2 g. of lithium copper chloride in 75 ml. of tetrahydrofuran. After 1 hour stirring at -10° C., the solution is evaporated, and the resultant oil is distilled in vacuo to yield the colorless 1-bromo-14-methylpentadecane.
