NOVELTY - Producing an alcohol compound (I) comprises reducing an amine compound (II) in the presence of an amine borane complex (III).    USE - The method is useful for producing alcohol and epoxyketone compounds (all claimed), where the epoxyketone compound is useful as an intermediate of medicine, the alcohol includes methanol, ethanol, propanol, butanol, octanol, methoxyethanol or ethoxyethanol, and ketone includes acetone, methyl ethyl ketone, methyl butyl ketone or methyl isobutyl ketone.    ADVANTAGE - The method provides high yield of valuable alcohol and epoxyketone compounds with improved selectivity in a safe and eco-friendly.    DETAILED DESCRIPTION - Producing an alcohol compound of formula (I) comprises reducing an amine compound of formula (II) in the presence of an amine borane complex of formula ((R)3N.BH3) (III).
