Electric Literature of 2752-17-2,Some common heterocyclic compound, 2752-17-2, name is 2,2′-Oxydiethanamine, molecular formula is C4H12N2O, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
General procedure: The precursor quinoline tetramer acid (100 mg, 0.1 mmol, 2.05 equiv), HBTU (114 mg, 0.3 mmol, 3 equiv), and HOBt (27 mg, 0.2 mmol, 2 equiv) were dissolved in anhydrous DMF under nitrogen. DIEA (173 muL, 1 mmol, 10 equiv) was added and the reaction mixture was stirred at room temperature for 30 min. The diamine (1 equiv) was added and the reaction mixture was stirred at room temperature for 12 h. The reaction mixture was poured into water, extracted three times with toluene, dried over Na2SO4, filtered, and concentrated. The crude was purified by silica-gel chromatography eluting with toluene/ethyl acetate 90/10 v/v, yielding the expected compound as a yellow solid.
The synthetic route of 2752-17-2 has been constantly updated, and we look forward to future research findings.
