Electric Literature of 588-63-6,Some common heterocyclic compound, 588-63-6, name is (3-Bromopropoxy)benzene, molecular formula is C9H11BrO, 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.
A suspension of the phenoxypropyl bromide (44) (0.3 mL, 1.90 mmol, d=1.365), piperidone hydrochloride hydrate (0.44 g, 2.86 mmol), K2CO3 (1.05 g, 7.62 mmol), anhydrous Na2SO4 (0.54 g, 3.81 mmol) and KI (47 mg, 0.286 mmol) in MeCN (20 mL) was stirred at reflux conditions for 2.5 hrs. The mixture was cooled to RT, diluted with water and extracted with EA. The extract was dried over Na2SO4, filtered, concentrated and the residue was purified by flash column chromatography, eluent 5percent MeOH in EA, to afford title compound 45 (0.45 g, quant. yield) as oil. (0383) 1H NMR: 500 MHz, CDCl3, delta (ppm): 7.30-7.26 (m, 2H), 6.96-6.90 (m 3H), 4.06 (t, J=6.3 Hz, 2H), 2.78 (t, J=6.1 Hz, 4H), 2.66 (t, J=7.1 Hz, 2H), 2.46 (t, J=6.8 Hz, 4H), 2.04-1.99 (m, 2H). MS: 233.3 (calcd.), 234.1 (M+H+, found).
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route (3-Bromopropoxy)benzene, its application will become more common.
