A common heterocyclic compound, 2770-11-8, name is 2-(4-Chlorophenoxy)aniline, molecular formula is C12H10ClNO, its 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. 2770-11-8.
Preparation of l-(4-(2-(4-chIorophenoxy)phenylamino)azepan-l-yI)ethanoneSTX1762 C20H23ClN2O2, MW: 358.86To a solution of 2-(4-chlorophenoxy)phenylamine (113 mg, 0.51 mmol), 1-acetylazepan-4-one (159 mg, 1.02 mmol) and acetic acid (153 mg, 2.55 mmol) in DCE (4 ml), was added sodium triacetoxyborohydride (270 mg, 1.28 mmol). The reaction mixture was allowed to stir at room temperature for 10 days. On return, the reaction was quenched with saturated aqueous sodium sodium bicarbonateonate (15 ml) and extracted with ethyl acetate (2 x 15 ml). The combined organics were dried (MgSO4), filtered and concentrated in vacuo. Purification by flash chromatography then proceeded (eluent; 9:1 hexane:ethyl acetate to ethyl acetate) to afford the title compound as a pale yellow oil (67.1 mg, 37%).1H NMR (270 MHz, CDCl3): delta 1.49-2.27 (9H, m, 3 x CH2, CH3), 3.30- 3.72 (5H, m, 5 x CH), 4.10 (IH, br s, NH), 6.59-6.67 (2H, m, Ar-H), 6.78-6.89 (3H, m, Ar-H), 7.00-7.08 (IH, m, Ar-H), 7.21-7.24 ppm (2H, m, Ar-H). 13C NMR (67.93 MHz, CDC13): delta 21.9, 24.2, 25.3, 32.8, 33.0, 34.2, 35.2, 42.0, 45.0, 45.1, 48.3, 51.0, 52.0, 112.2, 118.6, 118.7, 125.4, 129.7, 129.8, 139.0, 142.8, 156.1, 156.2, 170.5 ppm. LCMS: EPO
The synthetic route of 2-(4-Chlorophenoxy)aniline has been constantly updated, and we look forward to future research findings.
