Versuchsvorschrift

To a solution of 1.12 g of 4-chlorobutanal and 5.3 ml of 3M sulfuric acid in 11 ml of tetrahydrofuran, at 0° C., was added an solution of 2.0 g of 6-amino-4-(3-chloro-4-fluoro-phenylamino)-7-methoxy-3-quinolinecarbonitrile in 40 ml of dimethylforamide. To this was added portionwise 0.4 g of sodium borohydride. After 1 hr another 1.0 g of aldehyde, 10 ml of dimethylforamide, and 5 ml of 3M sulfuric acid was added followed by the portionwise addition of 0.8 g of sodium borohydride. After 2 hrs, the mixture was poured into water and the Ph was adjusted to 9. The mixture was extracted with ethyl acetate several times. The organic solution was dried over magnesium sulfate and the solvent was removed giving the title compound as an oil which was used without additional purification.
