Reaktionsschritte
Combine 3-fluorobenzylamine (31.1 g, 0.248 mol), 2-chloroethanol (10 g, 0.124 mol) and water (30 g, 1.66 mol) and heat on a steam-bath for ˜5 hours. Add sodium hydroxide (15 g, 0.373 mol) to the cooled solution and heat the resulting mixture on a steam-bath for ˜30 minutes. Add water (˜50 mL) to dissolve the inorganic salts and extract the two-phase mixture twice with 25 mL and 13 mL portions of benzene. Combine the extracts and remove the water by co-distillation with benzene through a modified Claisen flask. The final desired compound may be purified with further distillation.
