실험 절차

Dimethyl methoxymalonate (25.0 grams, 0.15 mole) and a large excess of n-propyl alcohol (250 millilaters) were reacted in the presence of p-toluenesulfonic acid (1.36 grams) catalyst, In a manner similar to that described in Example LIII Part A, to give 33.23 grams (0.15 mole) of di-n-propyl methoxymalonate. NMR analysis of the product indicated the following:
