Participants

Reaction Steps

To a round bottom flask were added 5-(4-Aminocyclohex-1-en-1-yl)-1-(2,2-dimethylpropyl)-3-methyl-1,3-dihydro-2H-imidazo[4,5-b]pyridin-2-one (17-2) (0.0010 g, 0.028 mmol), DIPEA (0.050 mL, 0.286 mmol), HATU (0.0013 g, 0.034 mmol), 1-methyl-1H-imidazole-2-carboxylic acid (0.00467 g, 0.037 mmol), and NMP (1 mL). The reaction was stirred at room temperature overnight (˜14 hours), the reaction mixtures were then filtered & purified by reverse-phase chromatography (5-95% 0.1% TFA in H2O:acetonitrile) to give N-{4-[1-(2,2-Dimethylpropyl)-3-methyl-2-oxo-2,3-dihydro-1H-imidazo[4,5-b]pyridin-5-yl]cyclohex-3-en-1-yl}-1-methyl-1H-imidazole-2-carboxamide (17-3). HRMS m/z (M+H): calculated=423.2503; observed=423.2507.
