To a mixture of (RS)-2-(4-amino-phenyl)-morpholine-4-carboxylic acid tert-butyl ester (60 mg, CAS 1002726-96-6), 4-chlorobenzaldehyde (33.3 mg) and AcOH (123 μl) in THF (2 ml) was added sodium triacetoxyborohydride (68.5 mg). The reaction mixture was then capped and the mixture was shaken at 60° C. for 3 h. The crude reaction mixture was then concentrated in vacuo and the residue was purified by flash column chromatography (silica gel; gradient: 0% to 65% EtOAc in hexanes) to afford (RS)-2-[4-(4-chloro-benzylamino)-phenyl]-morpholine-4-carboxylic acid tert-butyl ester (68 mg, 78%) as a colourless oil. MS (ISP): 405.4 ([{37Cl}M+H]+), 403.4 ([{35Cl}M+H]+).
