Dissolved 3,4-dimethoxy-N-[3-(1,2,3,4-tetrahydro-isoquinolin-7-ylcarbamoyl)-benzyl]-benzamide (50.0 mg, 0.12 mmol) in 1 mL of DMF. To the mixture was added methyl bromoacetate (0.02 mL, 0.20 mmol) and K2CO3 (50 mg, 0.36 mmol). The mixture was stirred at room temperature overnight. LC-MS indicated the desired product. Dissolved in 5 mL of DMF and purified via prep HPLC (5%-95% CH3CN/H2O) to give 37 mg (7-{3-[(3,4-dimethoxy-benzoylamino)-methyl]-benzoylamino}-3,4-dihydro-1H-isoquinolin-2-yl)-acetic acid methyl ester.
