With the rapid development and complex challenges of chemical substances, the synthesis of new drugs is usually one of the most effective ways to increase yield.52244-70-9, name is 4-(4-Methoxyphenyl)-1-butanol, molecular formula is C11H16O2, molecular weight is 180.24, as common compound, the synthetic route is as follows.Formula: C11H16O2
4-Methylphenylsulfonic Acid 4-(4-Methoxyphenyl)butyl Ester (1) Pyridine (15 mL) was added drop wise to a cooled (0° C.) solution of 4-(4-methoxyphenyl)butanol (10.0 g, 0.055 mol) and p-toluenesulfonyl chloride (13.6 g, 0.072 mol) in dry chloroform (100 mL) under stirring. The reaction mixture was stirred overnight at room temperature. After this time, the reaction was quenched with 10percent HCl (300 mL) and extracted with chloroform. The organic fraction was washed with saturated NaHCO3, water and dried over magnesium sulfate. The solvent was removed under reduced pressure and the residue purified by flash chromatography (eluent:hexane/ethyl acetate 15:1) to provide 12.9 g (66percent) of 1 as clear oil. 1H NMR (360 MHz, CDCl3) delta 1.61 (m, 4H), 2.44 (s, 3H), 2.52 (m, 2H), 3.78 (s, 3H), 4.05 (m, 2H), 6.77 (d, 2H), 7.05 (d, 2H), 7.34 (d, 2H), 7.78 (d, 2H).
At the same time, in my other blogs, there are other synthetic methods of this type of compound,52244-70-9, 4-(4-Methoxyphenyl)-1-butanol, and friends who are interested can also refer to it.
