A solution of 50 ml of benzene, 4.0 g (22.7 mmole) of 2,6-dichloro-3-methylaniline, 10.67 ml (80.8 mmole) of trimethylsilyl bromide, and 13.1 ml (94.0 mmole) of triethylamine was heated at reflux over 42 hours. The product was isolated as described in Example 1 to provide 4.14 g (16.7 mmole, 73.5 percent yield) of 98.0 percent pure N-trimethylsilyl-2,6-dichloro-3-methylaniline as a light yellow oil, b.p. 64°-68° C. at 0.03 mm.
