Dimethylamine → (6-Chloro-3-dimethylaminomethyl-isoquinolin-5-yl)-acetic acid methyl ester

Participants

Reaction Steps

To a solution of (3-bromomethyl-6-chloro-isoquinolin-5-yl)-acetic acid methyl ester (500 mg, 1.52 mmol) in THF (50 mL) was added a 50% solution of dimethylamine in THF (20 mL). The reaction mixture was stirred for 30 min. at room temperature, followed by removal of the solvents in vacuo. The residue was purified by flash column chromatography (silica gel, gradient of CH2Cl2/MeOH 100:0 to 95:5) to afford the title compound as a yellow oil (445 mg, 1.52 mmol, 100%). MS (ES+): 293 (M(C15H1735ClN2O2)+H)+.
