Electric Literature of 103146-25-4,Some common heterocyclic compound, 103146-25-4, name is 4-(4-(Dimethylamino)-1-(4-fluorophenyl)-1-hydroxybutyl)-3-(hydroxymethyl)benzonitrile, molecular formula is C20H23FN2O2, 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.
In a 200-ml four-necked flask equipped with a stirrer and a thermometer, 1.5 g [(4.] [38] m mol) of [()-4- [4-DIMETHYLAMINO-1- (4′-FLUOROPHENYL)-1-HYDROXYBUTYL]-3-] hydroxymethylbenzonitrile was dissolved in 30 ml of toluene, then 0.45 g of Novozym 435 (product [OF NOVOZYMES),] 0.347 g (4.38 m mol) of pyridine, 4.38 m mol of various kinds of acids and 1.00 g (8.76 m mol) of vinyl butyrate were added, and stirred at [40C] for between 16 and 21.5 hours. The result is shown in Table 4. Example 6 In a 200-ml four-necked flask equipped with a stirrer and a thermometer, 3.0 g [(8.] 76 m mol) of [( : L)-4- [4-DIMETLIYLAMINO-L- (41-FLUOROPHENYL)-L-HYDROXYBUTYL]-3-] hydroxymethylbenzonitrile was dissolved in 30 ml of toluene, then 0.9 g of Novozym [435] (product [OF NOVOZYMES),] 0.693 g (8.76 m mol) of pyridine, 8.76 m mol of various kinds of acids and 2.00 g (17.52 m mol) of vinyl butyrate were added, and stirred at [40C] for between 15.5 and 16.5 hours. The results are shown in Table 5.
The synthetic route of 103146-25-4 has been constantly updated, and we look forward to future research findings.
