Procedure

A solution of boron tribromide in methylene chloride (98.75 mL of a 1M solution in methylene chloride) is added to a mixture of 1-(2-bromo-5-methoxyphenyl)-3-methyl-s-triazine-2,4,6(1H,3H,5H)-trione (14.4 g, 0.438 mol) in methylene chloride at 0° C. The reaction mixture is stirred at room temperature for 1 hour and filtered to obtain a solid. The solid is washed with water and air-dried to give the title product as a white solid, mp 265°-270° C.
