Procedure
330 g (1 mol) of 2,4,6-tribromoaniline was reacted as described in Example 1 with 207 g (1.02 mol) of [2-(chloroformyl-)2-(methyl)ethyl-]methyl phosphinic acid chloride (prepared as described by V. K. Khairullin et al., C.A. 69, 106816 k (1968)). After hydrolysis with 6 liters of water, the resulting [2-(2,4,6-tribromophenylcarbamoyl-) 2-(methyl)ethyl-]methyl phosphinic acid was filtered off and dried at 80° C under vacuum.
