Participants

Reaction Steps

To a round bottom flask was added trans-N1-(5-methylpyridin-2-yl)cyclohexane-1,4-diamine dihydrochloride (intermediate 31, 0.2108 g, 0.758 mmol), 2-(3-chloropyrazin-2-yl)-2-methylpropanoic acid (intermediate 29, 0.182 g, 0.909 mmol), HATU (0.375 g, 0.985 mmol), and triethylamine (0.422 ml, 3.03 mmol) in dichloromethane (1.515 ml) to stir at room temperature. After 4 hours the solvent was evaporated off. The crude product was adsorbed onto a plug of silica gel and chromatographed through a Biotage SNAP HP-silica gel column (25 g), eluting with a gradient of 0% to 5% methanol in dichloromethane, to provide 2-(3-chloropyrazin-2-yl)-2-methyl-N-(trans-4-((5-methylpyridin-2-yl)amino)cyclohexyl)propanamide (0.2148 g, 0.554 mmol, 73.1% yield).
