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. 29632-73-3, name is 2-Bromo-4-iodoaniline, A new synthetic method of this compound is introduced below., Computed Properties of C6H5BrIN
To a solution of (10) (570 mg, 1.9 mmol) in dry toluene (8 mL), was added PPh3 (65.5 mg, 0.2 mmol) and Pd(OAc)2 (47.5 %, 60 mg, 0.1 mmol). tert-Butyl Acrylate (370 mu., 2.5 mmol) and NEt3 (420 mu., 3.0 mmol) were added and the flask was stirred at reflux overnight. The reaction was allowed to cool and washed with saturated aqueous NH4C1, brine, extracted with DCM, dried (Na2S04), filtered and concentrated. Purification by column chromatography (Hexane:EtOAc = 12: 1, 9: 1, 4: 1) provided the title compound as a brown oil (238.5 mg, 0.8 mmol, 64 %) Rf : 0.23 (Hexane:EtOAc, 4: 1). 1H NMR (400 MHz; CDC13,): delta 1.51 (9H, s, C(CH3)3), 6.15 (1H, d, J = 15.8 Hz, CH), 6.69 (1H, d, J = 8.1Hz, ArCH), 7.23 (1H, d, J = 8.2 Hz, ArCH), 7.40 (1H, d, J = 15.8 Hz, CH), 7.55 (1H, s, ArCH). 13C NMR (100 MHz; CDC13,): delta 28.2, 80.2, 109.0, 115.3, 117.0, 126.0, 128.4, 132.4, 142.3, 145.7, 166.6.
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.
