16.8 g (0.1 mole) Ethyl cyclohexylideneacetate, 9.2 g, (0.15 mole) nitromethane and 0.64 g (0.01 mole) potassium hydroxide (content 88%) in 40 mL dimethyl sulphoxide are stirred for 2 hours at 100° C. The reaction mixture is worked up analogously to Example 2 to give 20.5 g ethyl 1-nitromethyl-1-cyclohexaneacetate (89.4% of theory). According to GC., the content is 82.8% and 10.2% of starting compound and 4.1% of by-product are obtained (see Example 3).
