Reaction Steps

The final product was prepared according to Method F: A stirred solution of 1-[(4-fluoro-1-naphthyl)sulfonyl]-1,2,3,4-tetrahydroquinoline (50 mg, 0.15 mmol) and piperazine (80 mg, 0.9 mmol) in DMSO (1 ml) was heated at 95° C. over night. The reaction mixture was allowed to reach room temperature and was subsequently added dropwise into water. The formed solid was isolated, re-dissolved in MeOH and treated with an excess of 1M HCl in diethyl ether. Removal of the solvents in vacuo afforded the title compound (60 mg, 83%) as a white solid. 1H NMR (DMSO) δ 9.17 (br s, 2H), 8.23-8.06 (m, 3H), 7.61-7.55 (m, 1H), 7.48-7.38 (m, 2H), 7.29-7.23 (m, 1H), 7.19-7.12 (m, 1H), 7.09-6.98 (m, 2H), 3.78-3.71 (m, 2H), 3.44-3.30 (m, 8H), 2.42-2.32 (m, 2H), 1.57-1.48 (m, 2H); MS m/z (M+1) 408.
