Procedure

17.6 g (0.07 mol) of ethyl 4-nitro-benzamidoacetate dissolved in 250 ml of ethanol are hydrogenated in the presence of a catalyst (2 g of palladium on charcoal); the catalyst is filtered off, the filtrate is evaporated to dryness in vacuo, the residue is taken up in 100 ml of diisopropyl ether and the product is filtered off. 15 g (87% yield) of the stated product are obtained. Melting point: 93°-94° C.
