Procedure
A mixture of 0.092 parts of α-amino-2,6-dichlorobenzeneacetamide, 0.032 parts of 2-fluoronitrobenzene and 1 part of 1,3-dimethyl-2-imidazolidinone was stirred for 6 hours at 140° C. The product was extracted and the extract was dried, filtered and evaporated at 100° C. and 133-266 Pa. The residue was purified by column chromatography (HPCL, silica gel; CH2Cl2CH3OH 99:1→90:10), yielding 0.12 parts of (-)-2,6-dichloro-α-[(2-nitrophenyl)amino]benzeneacetamide (e.e.=90%).
