The resulting mixture was stirred at -10 C for 30 minutes then allowed to warm to room temperature overnight after which time the reaction mixture was cooled in an ice bath and slowly quenched with 50 mL saturated NEUCl. After stirring for 20 minutes the product was extracted into DCM. The combined DCM extracts were dried over MgSCk, filtered, and concentrated under reduced pressure. The residue was re-dissolved in ethyl acetate and washed with brine. The organic layer was filtered through a sintered glass funnel and the filtrate was dried over sodium sulfate, filtered, and concentrated under reduced pressure to dryness.

After all of sodium was dissolved, the mixture was evaporated to dryness. Then, 30 mL tolune was added and the mixture was dried down again by evaperation to give fresh NaOMe. To this was added dimethyl carbonate (300 mL) and 2-(2,6- dichlorophenyl)acetonitrile (25 g, 134.41 mmol). The resulting solution was allowed to reflux for 2 hours. The reaction progress was monitored by TLC (AcOEt: PE=I :4). The mixture was quenched by the addition of of 100 mL ice H2O. Then, the pH was adjusted to ca. 6 by the addition of AcOH . The resulting mixture was then extracted with EtOAc (3 x 100 ml). Combined organic layers were then concentrated down in vacuo to afford a residue that was purified by a column chromatography eluted with a 20:1 PE / AcOEt. This resulted in 27.8 g (85%) of methyl 2-cyano-2-(2,6-dichlorophenyl)acetate as a white solid. This was used for next step without further purification.
