Hydrochloric Acid → 4-(2-Aminoethoxy)phenol--hydrogen chloride (1/1)

Participants

Reaction Steps

4-(2-Aminoethyloxy)-phenol. In a Parr bottle the product from Preparation 8, Step 1. (10.7 g, 44.7 mmol) was dissolved in absolute EtOH (100 mL). The solution was treated with 37% HCl (9 g) and 10% Pd/C (1.8 g). The reaction mixture was de-aerated, then charged with hydrogen (initial pressure: 50 pso H2) and shaken for 16 h. The mixture was filtered and the filtrate was concentrated in vacuo to afford 4-(2-aminoethoxy)-phenol hydrochloride salt (7.22 g, 85%) as a beige solid. This material was used without further purification.
