Adding a certain compound to certain chemical reactions, such as: 110882-60-5, name is 3-Fluoro-5-nitrobenzonitrile, 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 110882-60-5, Recommanded Product: 3-Fluoro-5-nitrobenzonitrile
Example 1 Step 2. To solution of 1.0 eq IB in dry Et2O (0.06 M) at 00C was added dropwise a solution of diisobutyllithiumaluminum hydride (1.1 eq, 1.0 M in hexanes) by syringe. The resulting solution was kept at 00C overnight. The reaction mixture was added to a mixture of ice and glacial acetic acid. The reaction mixture was then diluted with ethyl acetate, and the aqueous layer was extracted with ethyl acetate two additional times. The combined organic layers were washed twice with saturated sodium bicarbonate, and once with brine. The organic layers were then dried over sodium sulfate, filtered and concentrated in vacuo. Purification over silica gel using 10% EtOAc/hexanes as the eluant afforded a yellow solid (100%) as an 80:20 mixture of 1C:1B. Example 1 Step 3. To cooled (00C) slurry of an 80:20 mixture of 1C:1B (1.0 eq) and boc-piperazine(about 2 eq) in a mixture of HOAc and DCM (4.8 M boc-piperazine in 1:1.4 v/v HOAc/DCM) was added sodium triacetoxyborohydride as a solid over about 5 minutes. The reaction was allowed to warm to RT and stirred for two hours. The reaction mixture was quenched with saturated sodium bicarbonate and diluted with ethyl acetate. The layers were separated and the aqueous layer was washed three times with ethyl acetate. The organic layers were combined and washed with brine, dried over sodium sulfate, and concentrated in vacuo. Purification by chromatography over silica gel using 50% ethyl acetate/hexanes as the eluant provided ID (67.7%) as a yellow oil.
