N-(3-chlorophenyl)formamide

Conditions: temp:60.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Acetic anhydride (189 ml, 2.0 mol) was mixed with formic acid (91 ml, 2.4 mol) at 0° C. and the mixture was stirred at 60° C. for 1 h and then cooled to 0° C. To the solution was added dropwise 3-chloroaniline (105.7 ml, 1.0 mol) and the mixture was stirred at room temperature for 18 h. After removal of solvent in vacuo, the residue was extracted with EtOAc-H2O. The organic layer was washed with 5% aqueous citric acid, saturated aqueous NaHCO3 and brine, dried over Na2SO4 and then concentrated. The residue was crystallized from iPr2O to give the title compound (115 g, 0.739 mol, 74%) as a colorless solid. cooled to 0° C the mixture was stirred at room temperature for 18 h After removal of solvent in vacuo the residue was extracted with EtOAc-H2O The organic layer was washed with 5% aqueous citric acid, saturated aqueous NaHCO3 and brine dried over Na2SO4 concentrated The residue was crystallized from iPr2O
