Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 32692-19-6, name is 5-Nitroindoline, A new synthetic method of this compound is introduced below., Recommanded Product: 32692-19-6
N,N-Dimethyl-2-(5-nitroindolin-1-yl)ethanamine (2) A solution of compound 1 (500 mg, 3.05 mmol) in DMF (10 mL) was treated with NaH (390 mg, 9.75 mmol, 60% wt in mineral oil) at 0 C. resulting in an orange mixture. It was then treated with 2-chloro-N,N-dimethylethanamine hydrochloride (877 mg, 6.09 mmol) resulting in a dark red mixture. The reaction was heated to 90 C. and stirred for 1.5 hours. After allowing the reaction to cool to room temperature, water (80 mL) was added, and the reaction was extracted into ethyl acetate (3*25 mL). The combined organic layers were washed with water (2*15 mL) and then with brine (10 mL), dried (Na2SO4), filtered, and concentrated. The residue was subjected to flash chromatography on silica gel:CH2Cl2 and then 2.5% 2M NH3 in methanol: 97.5% CH2Cl2 to give a brownish/red solid (400 mg, 56% yield). 1H-NMR (DMSO-d6) delta 7.96 (dd, J=2.1, 8.7 Hz, 1H), 7.79 (d, J=2.1 Hz, 1H), 6.49 (d, J=9.0 Hz, 1H), 3.72 (t, J=8.7 Hz, 2H), 3.39 (t, J=6.6 Hz, 2H), 3.04 (t, J=8.7 Hz, 2H), 2.44 (t, J=6.3, 2H), 2.18 (s, 6H).
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
