実験手順

To a solution of 6-(5-aminomethyl-pyridin-3-yl)-1-methyl-3,4-dihydro-1H-quinolin-2-one (example 36, 0.047 g, 0.177 mmol) in DMF (1 mL) were added 3,5-dimethylisoxazole-4-carboxylic acid (0.037 g, 0.266 mmol) and TBTU (0.063 g, 0.195 mmol) followed by Hünig's base (0.048 g, 0.372 mmol) and the reaction mixture was stirred at room temperature over night. The mixture was purified directly by reverse phase HPLC on a Gemini-NX column, eluting with a 20 to 98% MeOH—H2O (0.05% TEA) gradient to give the title compound (0.041 g, 59%) as a colorless solid. MS: 391.3 (M+H+).
