Versuchsvorschrift

To a stirred solution of 1-(4-(4-(5-chloro-4-(2-nitrophenoxy)pyrimidin-2-ylamino)-3-methoxyphenyl)piperazin-1-yl)ethanone (140 mg, 0.28 mmol) in 1,4-dioxane:water (10 mL:4 mL), Zinc dust (81 mg, 1.4 mmol) and ammonium chloride (74 mg, 1.4 mmol) were added, and the mixture was stirred at rt for 30 min. TLC showed completion of starting material (TLC system:5% methanol in chloroform (Rf): 0.3). The reaction mixture was filtered, concentrated, diluted with water (20 mL) and extracted with ethyl acetate (3×10 mL). The organic layer was separated, dried over sodium sulphate, and concentrated. Crude compound was washed with n-pentane to obtain 1-(4-(4-(4-(2-aminophenoxy)-5-chloropyrimidin-2-ylamino)-3-methoxy phenyl)piperazin-1-yl)ethanone as a pale yellow solid. (Yield: 90 mg, 68.7%). 1HNMR (DMSO-d6) δ 8.30 (s, 1H), 7.90 (s, 1H), 7.35 (d, 1H), 7.00 (m, 2H), 6.80 (d, 1H), 6.58 (m, 2H), 6.20 (br s, 1H), 4.90 (br s, 2H), 3.75 (s, 3H), 3.55 (m, 4H), 3.05 (m, 2H), 2.95 (m, 2H), 2.02 (s, 3H). Step-4. Preparation of N-(2-(2-(4-(4-acetylpiperazin-1-yl)-2-methoxyphenylamino)-5-chloro pyrimidin-4-yloxy)phenyl)acrylamide:
