ABSTRACT OF THE DISCLOSURE An inert organic solvent dispersion of alkali metal hydroxide is prepared by mixing an alkali metal hydroxide, an inert organic solvent selected from aromatic hydrocarbons and halogenated aromatic hydrocarbons and a stabilizer and heating and stirring at the temperature for forming the pasty alkali metal hydroxide and cooling the dispersion. The dis- persion of alkali metal hydroxlde is used in the reaction of an active methylene compound with an organoalkyl halide such as the reaction of a halophenylacetonitrile with an isopropyl halide to obtain an .alpha.-isopropyl halophenylacetonitrile.
