Reaction Steps

A mixture of diethyl(4-acetyl-2-nitrophenyl)malonate and diethyl malonate (54.1 g) prepared by step a) was dissolved in 4M HCl (800 mL)/dioxane (800 mL), and the solution was stirred at 100° C. for 8 hours. After cooling, dioxane was removed in vacuo, and the aqueous layer was extracted with chloroform (200 mL×1, 100 mL×2). The organic layers were combined, dried over magnesium sulfate, filtered, and the solvent was removed in vacuo to give the object compound (23.1 g, quantitatively) as a brown solid.
