Reaction Steps

To a solution of 1-(4-methyl-1-piperazinyl)-3-isoquinolinylamine (commercially available; 0.26 g, 1.07 mmol) and pyridine (0.60 mL, 7.51 mmol) in CH2Cl2 (3.0 mL) was added benzenesulfonyl chloride (151 μL, 1.18 mmol) in CH2Cl2 (1 mL). The mixture was stirred at room temperature for 16 hours and left in the refrigerator for 24 hours. The precipitate was collected by filtration to give 0.255 g (57%) of the pure product as the HCl-salt: 1H NMR (DMSO-d6) δ 10.93 (s, 2H), 7.96–7.90 (m, 3H), 7.79–7.75 (m, 1H), 7.64–7.56 (m, 4H), 7.44–7.38 (m, 1H), 7.01 (s, 1 H9, 3.70–3.15 (m, partly obscured by solvent signal, 8H), 2.79 (s, 3H); MS (posEI-DIP) m/z 382 (M+).
