Aluminium lithium hydride → (4-Methoxycyclohexyl)methanol

Temperatur

40 °C

13.7 ml (27.5 mmol) of lithium aluminium hydride solution (2M in THF) was diluted with 82 ml of methyl tert-butyl ether, and a solution of 4.30 g (25.0 mmol) of methyl 4-methoxycyclohexanecarboxylate (cis/trans isomer mixture) in 82 ml of methyl tert-butyl ether was then added dropwise. The reaction solution was stirred at 40° C. for another 6 h and the reaction was then terminated by addition of 10 ml of water and 10 ml of aqueous 10% strength potassium hydroxide solution. The organic phase was decanted, dried over sodium sulphate and filtered, and the solvent was removed under reduced pressure. Yield: 3.24 g (90% of theory)
