Reaction Steps
A mixture of 1-ethyl-7-chloro-4-quinolon-3-ylcarboxylic acid (182 mg) and 1-(4-pyridyl) piperazine (125 mg ) was heated to 200° C. for 20 minutes. The mixture was cooled and methanol (5 ml) was added. The resulting solid was filtered and washed with methanol (10 ml) to give the title compound (68 mg), as a solid: NMR (d6DMSO) δ 1.4(t,3H), 3.75°-3.85(m,4H), 3.9-4.0(m,4H), 4.55(q,2H), 6.9(d,1H), 7.2(d,2H), 7.3(dd,1H), 8.2(d,1H), 8.3(d,2H), 8.9(s,1H); m/e 379(M+H)+
