N-Methylaniline → HCID 123670657, compound

In a 500 ml Schlenk flask, 64.2 grams (g) (0.6 mol) N-methylaniline and 131 g (1.0 mol) di-isopropylaminosilane were stirred at ambient temperature under a nitrogen atmosphere for 24 hours. The relatively lower boiling point by-product di-isopropylamine was removed with vacuum at a pressure of 20 mmHg and room temperature (25° C.). The reaction mixture was stirred for another 24 hours. The end-product phenylmethylaminosilane (73.6 g, 89.5% yield) was obtained by vacuum distillation with a boiling point of 60° C. at 5 mm Hg. The end-product was characterized by mass spectroscopy (MS) which is provided in FIG. 1 and shows, among other things, peaks at 137, 122, 106, 91, and 77. The molecular weight of the phenylmethylaminosilane was 137.27.
