Related Products of 13726-21-1, These common heterocyclic compound, 13726-21-1, name is 2-(4-Chloro-3-methoxyphenyl)acetonitrile, 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.
BBr3 (17 g, 66 mmol) was slowly added to a solution of 2-(4-chloro-3-methoxyphenyl)acetonitrile (12 g, 66 mmol) in dichloromethane (120 mL) at -78 C. under N2. The reaction temperature was slowly increased to room temperature. The reaction mixture was stirred overnight and then poured into ice and water. The organic layer was separated, and the aqueous layer was extracted with dichloromethane (40 mL*3). The combined organic layers were washed with water, brine, dried over Na2SO4, and concentrated under vacuum to give (4-chloro-3-hydroxy-phenyl)-acetonitrile (9.3 g, 85%). 1H NMR (300 MHz, CDCl3) delta 7.34 (d, J=8.4 Hz, 1H), 7.02 (d, J=2.1 Hz, 1H), 6.87 (dd, J=2.1, 8.4 Hz, 1H), 5.15 (brs, 1H), 3.72 (s, 2H).
Statistics shows that 2-(4-Chloro-3-methoxyphenyl)acetonitrile is playing an increasingly important role. we look forward to future research findings about 13726-21-1.
