Procedure

A mixture of 2.0 g of 4-chloro-8-fluoroquinoline and 2.8 g of 2-(2-thienyl)ethyl amine was heated under nitrogen to 160°-165° C. for two hours, then cooled and combined with 200 mL of a 50:50 mixture of ammonium hydroxide and water. The product was extracted into CH2Cl2, which was then concentrated to dryness. The residue was recrystallized from pentane/CH2Cl2 to give 1.0 g of the title product. Yield 34.5%. M.P. 157°-158° C.
