Reaction Conditions

Reaction Steps

A mixture of 224 g of reduced iron, 13.4 g of ammonium chloride, 1,000 ml of isopropyl alcohol, and 200 ml of water was prepared, and then 237 g of ethyl p-nitrobenzoylacetate was added thereto in small amounts at temperatures ranging between 50° and 70° C. They were reacted at 70° C. for 1 hour and then the reaction solution was filtered. Then, 1,000 ml of water was added to the filtrate and cooled to 5° C., and crystals precipitated were collected by filtration to yield 172 g of yellow ethyl p-aminobenzoylacetate crystals, m.p., 82°-4° C.
