Benzyl Alcohol → HCID 18370146, Verbindung

Temperatur

-15 °C

A solution of 5-methyl-2-oxohexanoic acid (0.288 g.) in methylene chloride (1 ml.) was added during 15 minutes to a stirred solution of dicyclohexylcarbodiimide (0.412 g.) and benzyl alcohol (0.432 g.) in methylene chloride (10 ml.) which was cooled to -15° C., and the mixture was stirred at that temperature for 1 hour, then at laboratory temperature for 30 minutes, and was then evaporated to dryness. Water (1 ml.), diethyl ether (2 ml.) and acetic acid (0.01 ml.) were added and the mixture was kept at laboratory temperature for 12 hours and then evaporated to dryness. The residue was purified by chromatography on a silica gel column using toluene as eluant and there was thus obtained benzyl 5-methyl-2-oxohexanoate as an oil.
