Procedure
NaH 80% (0.0918 mole) was added portionwise at 0° C. under N2 flow to a solution of intermediate (1) (0.0612 mole) in DMF (100 ml). The mixture was stirred at 0° C. under N2 flow for 1 hour. CH3l (0.0918 mole) was added dropwise at 0° C. The mixture was stirred at 50° C. for 12 hours, then poured out on ice and extracted with EtOAc. The organic layer was separated, washed with H2O, dried, filtered and the solvent was evaporated, yielding 17.1 g of 2,6-dichloro-α,α-dimethyl-4-nitrobenzeneacetonitrile (intermediate 2).
