Yield:923688-20-4 96.9%

Reaction Conditions:

with potassium carbonate in dimethyl sulfoxide at 130; for 4 h;

Steps:

1.1. General procedure for the synthesis of compound (1), (2) and (18).

General procedure: A mixture of 5-trifluoromethyl-2 (1H)-pyridone(20 mmol)and potassium carbonate (32 mmol) in DMSO (100 mL) reacted with 3-chloro-4-fluoro-nitrobenzene, 1-(chloromethyl)-4-nitrobenzene or1-(chloromethyl)-2-nitrobenzene (30 mmol) at 130.After cooling the reaction solution was diluted with 12% ammonia300 mL. The precipitate was filtrated off . The residue was recrystallized with EtOAc to give compounds(1, 2, 18) respectively.
