247940-06-3, 2-(Dicyclohexylphosphino)biphenyl is a chiral-phosphine-ligands compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

Example 76 3-[2-(2,4-Dichloro-Phenyl)-Ethoxy]-4-Methoxy-N-(1-Phenyl-piperidin-4-Ylmethyl)-Benzamide A mixture of 100 mg (0.2 mmol) 3-[2-(2,4-Dichloro-phenyl)-ethoxy]-4-methoxy-N-piperidin-4-ylmethyl-benzamide, 50 mg (0.32 mmol) Bromobenzene, 70 mg sodium-t-butoxide in 5 ml dioxane were purged with argon for 10 min. Then 37 mg of 2-(Dicyclohexylphosphino)biphenyl and 20 mg Pd2(dba)3 were added under argon and the mixture refluxed overnight. The residue was taken up in 3 ml saturated NaHCO3 solution and filtered through a chem elut cartridge by elution with ethyl acetate. Subsequent removal of the solvent under reduced pressure and purification by preparative HPLC (C18 reverse phase column, elution with a H2O/MeCN gradient with 0.5% TFA) the fractions containing the product were evaporated and lyophilised.

247940-06-3, The synthetic route of 247940-06-3 has been constantly updated, and we look forward to future research findings.

247940-06-3, 2-(Dicyclohexylphosphino)biphenyl is a chiral-phosphine-ligands compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

EXAMPLE 32A 3′-ethoxy-6-methyl(1,1′-biphenyl)-3-carbonitrile A mixture of 3-chloro-4-methylbenzonitrile (3.03 g, 20 mmol), 3-ethoxyphenylboronic acid (4.98 g, 30 mmol), palladium acetate (74 mg, 0.4 mmol), 2-dicyclohexylphosphanyl-biphenyl (0.210g, 0.6 mmol), and KF (3.48g, 60 mmol) in THF (25 mL) at room temperature was stirred for 12 hours and concentrated. The concentrate was dissolved in ethyl acetate (10 mL), washed with brine, dried (MgSO4), filtered, and concentrated. The concentrate was purified by flash column chromatography on silica gel with 4:100 ethyl acetate/hexanes to provide 4.68 g (99%) of the desired product. MS (DCI/NH3) m/z 255 (M+NH4)+; 1H NMR (CDCl3) delta7.54-7.51 (m, 2H), 7.36-7.31 (m, 2H), 6.93 (m, 1H), 6.85-6.78 (m, 2H), 4.07 (q, 2H), 2.32 (s, 3H), 1.34 (t, 3H).

247940-06-3, As the paragraph descriping shows that 247940-06-3 is playing an increasingly important role.
