Reaction Steps

To a solution of 4-chlorobenzaldehyde (1 eq.) in MeOH was added ethylamine 70% in water (10 eq.). The reaction was stirred for 15 h at 20° C. under argon then NaBH4 (2 eq.) was added. The reaction was stirred at 20° C. for 5 h. The reaction was quenched with water then acidified with aqueous HCl (2M). The aqueous layer was washed with EtOAc. The organic layer was discarded. Aqueous NaOH (2M) was then added to the aqueous layer until pH=10 and the crude was extracted twice with EtOAc. The organic layers were combined, dried over MgSO4, filtered and concentrated under reduced pressure to afford (4-chloro-benzyl)-ethyl-amine.
