Procedure
A solution of 6-amino-1-(3-(piperidin-1-yl)propyl)-3,4-dihydroquinolin-2(1H)-one (0.065 g, 0.226 mmol) in dry ethanol (5 mL) was treated with methyl thiophene-2-carbimidothioate hydroiodide (0.129 g, 0.452 mmol) at room temperature and the resulting mixture was stirred for 64 hours. The reaction was transferred to a separatory funnel and diluted with ethyl acetate (30 mL) and saturated sodium hydrogen carbonate (20 mL). The aqueous was partitioned twice more with ethyl acetate (2×20 mL). The combined organics were washed with brine and dried (Na2SO4). Solvent was evaporated and crude was purified by column chromatography (2M ammonia in methanol:dichloromethane, 0-1:10-9). The product was dried under high vacuum. Yield: 46 mg of yellow solid (51%). 1H NMR (DMSO-d6) δ: 8.02 (d, J=3.9 Hz, 1H), 7.99 (d, J=3 Hz, 1H), 7.32 (d, J =4.8 Hz, 1H), 7.28 (d, J=6.3 Hz, 1H), 7.20 (s, 1H), 7.17 (s, 1H), 4.32 (br s, 2H), 3.98−3.93 (m, 2H), 3.45-3.40 (m, 4H), 3.16-3.10 (m, 4H), 2.95-2.90 (m, 4H), 2.61-2.56(m, 2H), 2.01-1.90 (m, 2H). MS (ESI): 397.2 (M+1). ESI-HRMS calculated for C22H29N4SO (MH+): 397.2056, Observed: 397.2073.
