HCID 68461457N-acetyl-N-[4-[3-chloro-4-(1-methyl-1H-imidazole-2-ylsulfanyl)-phenylamino]-3-cyano-7-(4-pyrrolidin-1-yl-piperidin-1-yl)quinolin-6-yl]acetamide

Versuchsvorschrift

To a cold (0° C.-5° C.) solution of 1.2 g (2.14 mmol) of 6-amino-4-[3-chloro-4-(1-methyl-1H-imidazole-2-ylsulfanyl)phenylamino]-7-(4-pyrrolidin-1-yl-piperidin-1-yl)quinoline-3-carbonitrile and 3.6 ml (22.6 mmol) of N,N-diethyl aniline in 18 mL of 1-methyl 2-pyrrolidinone is added dropwise 1.6 ml (21.2 mmol) of acetyl chloride. The resulting mixture is stirred at room temperature for 4 hours. The solvent is removed in vacuo to yield a residue, which is triturated with ether. A saturated solution of sodium bicarbonate is added to the resulting solid and the mixture is stirred, collected by filtration and dried in vacuo. Purification by silica gel chromatography (gradient 95:5 methylene chloride/methanol to 4:1 methylene chloride/methanol) gives 738 mg of N-acetyl-N-[4-[3-chloro-4-(1-methyl-1H-imidazole-2-ylsulfanyl)-phenylamino]-3-cyano-7-(4-pyrrolidin-1-yl-piperidin-1-yl)quinolin-6-yl]acetamide as a beige solid, mp 245-247° C.
