Procedure

Trimethyl tin hydroxide (0.388 g, 2.14 mmol) was added to a solution of methyl 2-(7-cyano-2-oxoquinolin-1(2H)-yl)acetate (0.104 g, 0.429 mmol) in 1,2-dichloroethane (5 mL) and the resulting suspension was stirred at reflux for 4 h. The reaction mixture was diluted with dichloromethane and washed with 1N aqueous HCl. Filtration of the organic phase provided 87 mg (89%) of 2-(7-cyano-2-oxoquinolin-1(2H)-yl)acetic acid. Retention time (min)=0.987, method [1], MS (ESI) 229.1 (M+H).
