1,2-Dichloroethane → 3-chloro-4-methoxy-N-[3-(2-methyl-1,2,3,4-tetrahydro-isoquinolin-7-ylcarbamoyl)-benzyl]-benzamide

関与物質

反応手順

A solution of 3-chloro-4-methoxybenzoic acid dihydrochloride (29 mg, 150 mmol), EDC (30 mg, 150 mmol), HOBt (22 mg, 150 mmol), and TEA (0.057 mL, 408 mmol) in anhydrous DMF (5 mL) was stirred at room temperature for 30 min. To this was added 3-aminomethyl-N-(2-methyl-1,2,3,4-tetrahydro-isoquinolin-7-yl)-benzamide. (50 mg, 136 mmol) and the solution stirred at room temperature for 24 h. The reaction was diluted EtOAc (100 mL) and quenched with sat. NH4Cl (100 mL). The organic fraction was dried (Na2SO4). The residue was purified by flash chromatography using a methanol/methylene chloride gradient to provide 31 mg of 3-chloro-4-methoxy-N-[3-(2-methyl-1,2,3,4-tetrahydro-isoquinolin-7-ylcarbamoyl)-benzyl]-benzamide. MS, electrospray, 464 (M+H).
