실험 절차

To a solution of (S)-3-(5-methyl-2-oxo-1,2-dihydro-imidazo[4,5-b]pyridin-3-yl)-hexanoic acid ethyl ester (247 mg, 0.85 mmol) in DMF (5 mL) were added K2CO3 (234 mg, 1.7 mmol) and (1,4-dimethyl-1H-indol-3-ylmethyl)-trimethyl-ammonium iodide (438 mg, 1.27 mmol). The reaction mixture was heated to 60° C. for 48 hours. The reaction mixture was diluted with ethyl acetate and washed with water (×4). The organic phase was dried over Na2SO4 and concentrated. The resulting residue was purified by silica gel preparative TLC using 98:2 CH2Cl2:MeOH as an eluent to afford 170 mg (45%) of the title compound. LCMS, M++1, m/z: 449.47.
