Methanol → 3-Ethylaminophenol

Participants

Reaction Steps

A 1.0 M solution of borane-methyl sulfide in dichloromehtane (275 ml) was added dropwise to a solution of 3-acetamidophenol (161 g) in THF (800 ml) over about 1 to 2 hours. The mixture was heated to reflux temperature for about 4 hours and was then poured slowly into methanol (1 liter). The solvent was evaporated to a heavy syrup, which deposited crystals on cooling and scratching. The solid was collected by filtration and redissolved in methanol. Evaporation and recrystallization as above gave a 74% yield of the compound.
