Under the protection of inert gas, 2-methylphenylsulfonylhydrazide (1.1 mmol), benzonitrile (1.0 mmol), palladium catalyst (2 mol %) and biquinoline (bq, 3 mol %) were dispersed in an organic solvent (2 mL) ), then H2O (2 mmol) was added, and the temperature was raised to 80°C for 6 hours. Then the reaction solution was extracted three times with Et2O (5 mL), the organic phases were combined, and the solvent was spin-dried under reduced pressure. The obtained crude product was subjected to column chromatography on a silica gel column (300-400 mesh), and the eluents were petroleum ether and ethyl acetate. , to obtain the target product 2-methylbenzophenone. Chemical properties Colorless or light yellow transparent liquid. The melting point is about 134°C. Use as a pharmaceutical intermediate.
