Synthetic Route of 53087-13-1, A common heterocyclic compound, 53087-13-1, name is 1-(Benzyloxy)-3-bromobenzene, molecular formula is C13H11BrO, 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.
Iodine, warmed up with magnesium, was added to a suspension of magnesium tunings (1 .29 g, 52.8 mmol) in dry THF (50 ml_). The mixture was refluxed and about 5% of a solution of 3- bromophenol (13.9 g, 52.8 mmol) was added. When the reaction had started, the solution of the bromide was added drop-wise and the mixture was then refluxed for one more hour. The mixture was cooled down to about 5 C and a solution of the cyclopentanone (4.44 g, 52.8 mmol) in THF (50 mL) was added drop-wise. The mixture was stirred at rt for 72 h, then the reactio was quenched with cooled saturated ammonium chloride solution and extracted with diethyl ether (x3). The organic phase was washed with brine, dried (Na2S04), filtered and concentrated. The product was purified by silica gel chromatography (isohexane / EtOAc), which gave the title compound (8.5 g, 54%).
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.
