In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 796600-15-2, name is 2-Chloro-4-fluoro-3-methylbenzonitrile belongs to nitriles-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below. Safety of 2-Chloro-4-fluoro-3-methylbenzonitrile
Example 4 2-Chloro-4-(3-endo-hydroxy-8-azabicyclo[3.2.1]octan-8-yl)-3-methylbenzonitrile, hydrochloride (165RL90) 2-Chloro-4-fluoro-3-methylbenzonitrile (165RL87a, 55 mg, 0.32 mmol) and nortropine (165 mg, 1.29 mmol) was dissolved in pyridine (2 mL) and the mixture irradiated at 220 C. for 2 hours in a microwave oven. Dichloromethane (50 mL) was added and the mixture washed with hydrochloric acid (0.4 M, 2¡Á30 mL) followed by sat. sodium hydrogen carbonate (20 mL). The organic layer was dried over sodium sulfate, filtered and evaporated. The product was further purified by column chromatography using dichloromethane to give the title compound (16.2 mg, 18%). Rf=0.45 (CH2Cl2). LC/MS m/z 277 [M+H]+. 1H-NMR (CDCl3, 300 MHz) delta 7.37 (d, 1H, J=8.6, Ar-H), 6.78 (d, 1H, J=8.6, Ar-H), 4.20 (m, 1H, Tr-H), 3.80 (m, 2H, Tr-H), 2.37 (s, 3H, Ar-CH3), 2.32-2.22 (m, 4H, Tr-H), 1.98-1,81 (m, 4H, Tr-H).
The synthetic route of 796600-15-2 has been constantly updated, and we look forward to future research findings.
