실험 절차

To a solution of (R)-1-(2-(2-cyclopropylpyrimidin-4-yl)-3H-imidazo[4,5-b]pyridin-5-yl)piperidine-3-carboxylic acid (70 mg, 0.192 mmol) in N,N-dimethylformamide (10 mL) were added 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide (EDCl) (73.2 mg, 0.383 mmol), hydroxybenzotriazole (52 mg, 0.383 mmol), triethylamine (58.2 mg, 0.575 mmol), (1R,5S)-8-oxa-3-azabicyclo[3.2.1]octane (186 mg, 1.64 mmol) and 4-dimethylaminopyridine (3 mg) at room temperature. The reaction mixture was stirred for 18 h, poured into ice water, extracted with ethyl acetate, washed with cold water and concentrated. The crude was purified via preparative TLC (3% methanol in dichloromethane) to afford the title compound (9 mg). MS (ES+) (M+H) 446.3; LCMS retention time 1.816 min (Method F)
