Reaction Steps

To a solution of N1-(2-methylquinolin-4-yl)ethane-1,2-diamine (161 mg, 0.800 mmol) and triethylamine (0.350 ml, 2.51 mmol) in acetonitrile (5 ml) was added a solution of (E)-3-methylbut-1-ene-1-sulfonyl chloride (102 mg of step D) in dichloromethane (1 ml). The mixture was stirred 30 minutes at room temperature, concentrated under reduced pressure and the residue was purified by column chromatography over aluminum oxide using a gradient of methanol (2-10%) in dichloromethane to yield 83 mg of an off-white foam (0.25 mmol; 13% over 4 steps).
