These common heterocyclic compound, 621-50-1, name is 2-(3-Nitrophenyl)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. Recommanded Product: 621-50-1
NaH (4.34 g, 90.4 mmol) was stirred in a solvent of tetrahydrofuran (20 mL) at 0 C. The reaction solution was slowly added with 2-(3-nitrophenyl)acetonitrile (2.2 g, 13.6 mmol), and stirred for about 30 minutes at 0 C. The reaction solution was added with MeI (6.67 mL, 107 mmol), followed by stirring for about 12 hours at room temperature. The reaction mixture was added with an ice water. The organic layer was separated out and the aqueous layer was extracted with ethyl acetate. The organic layer was dried over anhydrous sodium sulfate, filtered, and concentrated under reduced pressure. The concentrated compound was purified using silica gel chromatography (EA:HEX=1:9) to obtain the title compound (0.6 g, 23%). 1H-NMR Spectrum (300 MHz, DMSO-d6): delta 8.33 (s, 1H), 8.22 (d, 1H), 7.91 (d, 1H), 7.65 (t, 1H), 1.81 (s, 6H). MS (ESI+, m/z): 191 [M+H]+
The synthetic route of 2-(3-Nitrophenyl)acetonitrile has been constantly updated, and we look forward to future research findings.
