Ethyl 2-(3-chloroisoquinolin-1-yl)acetate → 2-(3-Chloro-isoquinolin-1-yl)acetamide

Participants

Reaction Steps

(3-chloro-isoquinolin-1-yl)-acetic acid ethyl ester (2.5 g, 10 mmol) is dissolved in 4N NH3/MeOH (50 ml). The solution is transferred into an autoclave and kept at 120° C. for 48 hours. After cooling to RT the solvent is removed and the resulting crude product is purified on silica gel using methylene chloride (100%)→methylene chloride/methanol (95/5) as eluent, affording 2-(3-chloro-isoquinolin-1-yl)-acetamide as a pale yellow solid.
