Reference of 52798-01-3, These common heterocyclic compound, 52798-01-3, name is Methyl (4-cyanophenyl)acetate, 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.
(4-Cyano-phenyl)-acetic acid methylester (1.054 g, 6.02 mmol), hydroxylamine hydrochloride (0.690 g, 9.93 mmol) and sodium bicarbonate (0.834 g, 9.93 mmol) were dissolved in MeOH (12.03 mL) at RT. The mixture was stirred at 60 C for 5 h, diluted with EtOAc (200 mL) and 40 ml water added. The aqueous layer was extracted with EtOAc (100 mL). The combined organic phases were washed with brine (40 mL) and dried over sodium sulfate. Solvent was removed to yield 1.2 g (5.76 mmol) of yellow oil, which was dried on high vacuum over night. The crude mixture was used without further purification.
Statistics shows that Methyl (4-cyanophenyl)acetate is playing an increasingly important role. we look forward to future research findings about 52798-01-3.
