Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 25574-11-2, name is 3-(4-Bromophenyl)propan-1-ol. This compound has unique chemical properties. The synthetic route is as follows. COA of Formula: C9H11BrO

To a 0 C. mixture of 26A (7 g, 32.5 mmol) and NaHCO3 (3.28 g, 39.1 mmol) in DCM (200 mL) was added Dess-Martin periodinane (16.56 g, 39.1 mmol) and the reaction was allowed to slowly warm to rt overnight. The reaction was diluted with sat. aq. NaHCO3 (150 mL) and extracted with DCM (50 mL). The combined organic extracts were washed with brine, dried over Na2SO4, and concentrated in vacuo. The residue was chromatographed (SiO2; 80 g; A=Hex, B=EtOAc; 20 min gradient from 0% B to 40% B; flow rate=60 mL/min) to afford the title compound (4.06 g, 19.1 mmol, 58.5% yield) as a pale yellow oil. 1H NMR (500 MHz, CDCl3) delta 9.82 (t, J=1.2 Hz, 1H), 7.48-7.37 (m, 2H), 7.19-6.97 (m, 2H), 3.02-2.88 (m, 2H), 2.83-2.70 (m, 2H).
