Procedure

A suspension of 2-[(1-ethyl-2(1H)-quinolylidene)-1-hydroxyethylidene]indan-1,3-dione (1.72 g, 0.005 mol) in methylene chloride (25ml) is stirred as bromine (1.76 g, 0.011 mol) in methylene chloride is added in one lot. The solid dissolves initially, and a new solid precipitates. After 5 minutes the product is collected and washed with methylene chloride. Yield 3.25 g (98%)
