Adding a certain compound to certain chemical reactions, such as: 147754-12-9, name is 4-Fluoro-2-methylbenzonitrile, belongs to nitriles-buliding-blocks compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 147754-12-9, Recommanded Product: 4-Fluoro-2-methylbenzonitrile
a) 1.35 g 4-Fluoro-2-methyl-benzonitrile, dissolved in DMF, was added to 2.11 g 4-Hydroxy-piperidine-1-carboxylic acid tert-butyl ester and 0.6 g sodium hydride in 30 mL DMF. The mixture was stirred at room temperature (rt) until the reaction was complete. The reaction was quenched with water. The aqueous layer was extracted with ethylacetate (AcOEt) or methyl tert. butyl ether (MTB ether). The combined organic layers were washed with brine, dried and concentrated to to give 2.6 g (yield 81percent) 4-(4-Cyano-3-methyl-phenoxy)-piperidine-1-carboxylic acid tert-butyl ester. Mass: (C18H24N2O3): calcd. 316, found 261 [M+H-t(C4H9)]+
