Reference of 103146-25-4, A common heterocyclic compound, 103146-25-4, name is 4-(4-(Dimethylamino)-1-(4-fluorophenyl)-1-hydroxybutyl)-3-(hydroxymethyl)benzonitrile, molecular formula is C20H23FN2O2, 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.
To a stirred solution [OF RACEMIC 4- [4-DIMETHYLAMINO-1- (4-FLUORO-PHENYL)-1-HYDROXY-] [BUTYL]-3-HYDROXYMETHYL-BENZONITRILE] (0,29 mmol, 100 mg) and vinylbutyrate (0,29 mmol, [37 L)] in anhydrous toluene (2,925 ml) is added Novozymes 435, (0,2 mg) and 1,1 eq. Carboxylic acid. The reaction is heated to 40 degrees celcius and followed by HPLC. The enzyme is filtered off and washed with a small amount of toluene. The combined organic phases are evaporated in vacuo and subsequently analyzed on super critical fluid chromatography. Result is shown in table 19.
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.
