Procedure

A suspension of 5,6,7,8-tetrahydro-5-oxo-2(1H)-quinolinone (33.0 g), silver carbonate (35.0 g), benzyl bromide (44.4 g), and toluene (400 ml) was stirred at room temperature for 72 hrs. The mixture was filtered and the filtrate was concentrated. Trituration of the residue with petroleum ether gave 45.6 g (83%) of product.
