Reaktionsschritte
Diethyl (formylamino)malonate (22.0 g, 0.108 mol) was added to a stirred solution of sodium ethoxide in ethanol (prepared from 2.4 g of sodium and 250 mL of ethanol, 0.10 mol). After 5 min, 8-(bromomethyl)quinoline (22.0 g, 0.10 mol) was added and the solution was stirred for an additional 15 minutes. The solvent was removed under reduced pressure and the product was partitioned between ethyl acetate and water. The ethyl acetate was removed and the residual oil was crystallized from ether to give 19.9 g (58%) of diethyl (formylamino)(8-quinolinylmethyl)propanedioate, mp 120°-122° C. Anal. Calcd. for C18H20N2O5 : C, 62.78; H, 5.85; N, 8.14. Found: C, 62.53; H, 6.03; N, 8.07.
