Reaction Steps

To a suspension of [2-(2-chloro-4-nitro-phenyl)-ethyl]-(4-fluoro-benzyl)-amine (3.1 g, 10 mmol) in DCM (31 mL) was added 15% HCl in dioxane (2.4 mL, 10 mmol) at 0° C. and the mixture was maintained for 1 hour at 0° C. After completion of salt formation, the volatiles were removed under reduced pressure. A mixture of 4:1 hexane and ethyl acetate (50 mL) was added to the residue and this was stirred for 15 minutes. The solvent was removed by filtration under suction and the solid was dried under reduced pressure to afford crude title product (2.8 g, 80%).
