Reaction Steps

To a solution of 4-(4-methyl-1-piperazinyl)-1-naphthylamine (prepared according to methods A and B) (0.099 g, 0.409 mmol) and pyridine (231 μL, 2.86 mmol) in CH2Cl2 (3.0 mL) was added 4-methylbenzenesulfonyl chloride (0.078 g, 0.409 mmol) in CH2Cl2 (1.0 mL). The solution was stirred at room temperature for 16 hours and then washed with saturated aqueous NaHCO3, dried with Na2SO4, filtered and concentrated. The crude product was purified via column chromatography (SiO2, CHCl3→CHCl3/MeOH/NH3 9:1:0.4%) to give the pure base which was converted to its HCl-salt: yield 110 mg (62%); 1H NMR (DMSO-d6) δ 10.86 (br s, 1H), 10.02 (s, 1H), 8.11-8.03 (m, 2H), 7.60-7.56 (m, 2H), 7.55-7.44 (m, 2H), 7.33-7.30 (m, 2H), 7.09-7.06 (m, 1H), 7.04-7.01 (m, 1H), 3.55-3.32 (m, 6H), 3.19-3.10 (m, 2H), 2.86 (s, 3H), 2.34 (s, 3H); MS (posES-FIA) m/z=395.1665 (M+H) (calc 395.1667).
