In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 53087-13-1 as follows. HPLC of Formula: C13H11BrO
1.85 g of magnesium was suspended in 15 ML of diethyl ether, to which a catalytic amount of iodine was added and then a solution of 20.00 g of 1-(benzyloxy)-3-bromobenzene in 40 ML of diethyl ether was added dropwise and this mixture was stirred for 8 hours while heating it under reflux.. The reaction mixture was cooled to 5C, to which a solution of 6.72 ML of cyclopentanone in 20 ML of diethyl ether was added dropwise, and this mixture was stirred for one hour at room temperature.. Then an aqueous solution of ammonia chloride was added to the ice-cooled reaction mixture, and the organic phase was separated therefrom.. After the resultant organic phase was washed with water and a saturated sodium chloride solution successively, the washed phase was dried over anhydrous magnesium sulfate, and the solvent was distilled out under reduced pressure.. The resultant residue was purified by silica gel column chromatography [eluent; hexane:ethyl acetate=10:1] to yield 7.65 g of 1-[3-(benzyloxy)phenyl] cyclopentanol as yellow oil. NMR(400MHz,CDCl3) delta value: 1.52(1H,s), 1.79-1.88(2H,m), 1.93-2.04(6H,m), 5.08(2H,s), 6.85(1H,ddd,J=8.4,2.8,1.2Hz), 7.08(1H,ddd,J=7.6,1.6,0.8Hz), 7.16-7.17(1H,m), 7.24-7.46(6H,m)
