Versuchsvorschrift

A solution of the product of step (i) (420 mg, 2 mmol) in THF (15 ml) was added to a suspension of lithium aluminium hydride (380 mg, 10 mmol) in THF (15 ml) with stirring at 0° C. under argon. After 1 hour a saturated aqueous solution of sodium carbonate (1 ml) was added dropwise and the mixture was stirred for a further 15 minutes before being filtered through a pad of diatomaceous earth, washing well with ethyl acetate. The filtrate was evaporated to give 1-hexyl-5-hydroxymethylimidazole (349 mg, 96% yield) as a solid;
