Procedure

Prepare a solution of 53.5 g (0.477 mol) of potassium tert.-butanolate in 400 ml of dimethylformamide. Cool the resulting solution to −10° C. and add thereto, over the course of about 1 hour, a solution of 40 g of 4-chlorophenoxyacetonitrile (0.24 mol) and 37 g of 2-nitronaphthalene (0.213 mol) in 200 ml of dimethylformamide. After 2 hours at −5° C., pour the mixture into 4 liters of water containing 1 liter of concentrated hydrochloric acid and extract the aqueous phase with 3×500 ml of dichloromethane. Wash the organic phase with 300 ml of water, dry it over magnesium sulphate, filter and then evaporate off the solvent.
