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. 24468-88-0, name is N-Benzyl-2-bromo-N-(2-bromoethyl)ethanamine, A new synthetic method of this compound is introduced below., Safety of N-Benzyl-2-bromo-N-(2-bromoethyl)ethanamine
To a 0 C solution of 6,7-dihydro-5H-cyclopenta[b]pyridin-5-one (1.70 g, 12.77 mmol) in DMF (20 mL) under nitrogen atmosphere was added NaH (60% dispersion in mineral oil, 982 mg, 24.55 mmol) in three portions, and the mixture was heated to 60 C, stirred for 1 h at thistemperature. Then N-benzyl-2-bromo-N-(2-bromoethyl)ethan-1-amine (4.54 g, 14.14 mmol) was added and stirred at 60 C for another 1 h. After cooling to RT, the reaction mixture was quenchedwith water (80 mL), extracted with EA (3 > 80 mL). The combined organic layers were washed with water (3 x 80 mL), dried over anhydrous Na2504, filtered and concentrated under reduced pressure. The residue was purified by silica chromatography (eluting with EA) to give1?-benzylspiro[cyclopenta[b]pyridine-6,4?-piperidin]-5(7H)-one (1.14 g). MS: m/z 293 (M+H).
The synthetic route of 24468-88-0 has been constantly updated, and we look forward to future research findings.
