2-ETHOXY-MALONIC ACID DIETHYL ESTER Use and Manufacturing
Preparation of compounds of formula (I) in scheme 42-Ethoxy-malonic acid diethyl ester[0050] A mixture of diethyl oxalate (39.23 ml, 1.12 eq.) and ethylethoxyacetate (34.95 ml, 1 eq.) was added dropwise to a slurry of sodium ethoxide (18.64 g, 1.07 eq.) in toluene (100 ml) at 45-50°C. After dropping, the resulting solution was heated to 70-80°C for 2 hrs and poured into 70 ml of 14percent HC1 with cooling. The resultant mixture was extracted with EA and the combined organic layers were washed with brine and dried in vacuo to give 55.86 g (93.7percent) of a product.Part B Preparation of Part B Preparation of Take 50g (231.4mmol)
