Reaction Steps

A solution of 4-chloro-3-(trifluoromethyl)benzeneacetonitrile (0.114 mol) in THF (100 ml) was added dropwise at RT to a solution of 1,2,3-trichloro-5-nitrobenzene (0.114 mol) and N,N,N-triethylbenzenemethanaminium chloride (3 g) in NaOH 150 ml) and THF (100 ml). The mixture was stirred at RT for 2 hours, then poured out on ice, acidified with a concentrated HCl solution and extracted with CH2Cl2. The organic layer was separated, dried, filtered and the solvent was evaporated. The residue was crystallized from DIPE. The precipitate was filtered off and dried, yielding 40.4 g (86.5%) of (±)-2,6-dichloro-α-[4-chloro-3-(trifluoromethyl)phenyl]-4-nitrobenzeneacetonitrile (interm. 1).
