methyl 2-(7-bromo-2-oxoquinolin-1(2H)-yl)acetate → methyl 2-(7-cyano-2-oxoquinolin-1(2H)-yl)acetate

Participants

Reaction Steps

CuCN (0.211 g, 2.36 mmol) and Pd(PPh3)4 (0.136 g, 0.118 mmol) were added to a solution of methyl 2-(7-bromo-2-oxoquinolin-1(2H)-yl)acetate (0.35 g, 1.18 mmol) in DMF (1 mL) in a screw cap vial. The vial was sealed and placed into a oil bath at 120° C. and the reaction mixture was stirred for 18 h. The resulting mixture was diluted with Et2O and washed with brine. The organic phase was separated, dried (Na2SO4), filtered, concentrated under vacuum and the residue was purified on a silica gel column to give methyl 2-(7-cyano-2-oxoquinolin-1(2H)-yl)acetate (0.204 g, 71%). Retention time (min)=1.464, method [1], MS (ESI) 243.1 (M+H).
