Hydrochloric Acid → Azepan-4-ol--hydrogen chloride (1/1)

Participants

Reaction Steps

To a solution of tert-butyl 4-hydroxyazepane-1-carboxylate (1.00 g, 4.65 mmol) in ethyl acetate (23 ml) was added 4N hydrogen chloride in ethyl acetate (23 ml, 92.0 mmol). The mixture was stirred at room temperature for 5 hours. The mixture was concentrated in vacuo to afford azepan-4-ol hydrochloride as a pale yellow oil (710 mg, 4.65 mmol, >99%). This compound was used for the next reaction without further purification.
