Procedure

Diethyl methoxymalonate (31.0 grams, 0.2 mole), prepared in Example LIII Part A, sodium hydride (3.91 grams of 60% reagent, 0.2 mole), methyl iodide (46.27 grams, 0.3 mole) and 15-crown-5 (2 drops) were reacted in 300 milliliters of N,N-dimethylformamide in a manner similar to that described in Example LII Part A to give 23.77 grams (0.1 mole) of diethyl methoxy(methyl)malonate. NMR analysis of the product indicated the following:
