Hydrazine hydrate (1:1) → 2-{4-[(Butan-2-yl)oxy]phenoxy}ethan-1-amine

Participants

Reaction Steps

To 4-(1-methylpropoxy)phenol (44.3 mmol) in 25 ml of DMF is added, under N2, potassium carbonate (51.0 mmol) followed by dropwise addition of N-(bromoethyl)phthalimide (51.0 mmol) in 30 ml of DMF. The mixture is stirred at RT overnight. Water is then added and the aqueous phase is extracted with ether. The combined organic layers are washed with 5% sodium hydroxide, with water and with brine, dried and the solent removed to give N-{2-[4-(1-methylpropoxy)phenoxy]ethyl}phthalimide. Following the procedures of Example 7, the above phthalimide (5.7 mmol) is reacted with hydrazine hydrate (5.7 mmol) to give 2-[4-(1-methylpropoxy)phenoxy]ethylamine.
