Benzylamine → N-[(Trimethylsilyl)methyl]benzylamine

Participants

Reaction Conditions

Reaction Steps

A mixture of 264 mL (2.42 mol) of benzylamine and 97.7 g. (0.796 mol) of chloromethyltrimethylsilane was heated to 200° C. for 2.5 h then cooled to 10° C. A 0.1M sodium hydroxide solution (400 mL) was added and the product was extracted with 3×200 mL of diethyl ether. The combined organic phase was washed with 100 mL of water, dried over anhydrous magnesium sulfate, filtered and concentrated under reduced pressure. The product was distilled at 115°-125° C. and 5 mm of Hg to give 125.4 g (81% yield) of N-trimethylsilylmethyl benzylamine as a clear liquid; 1H NMR (CDCl3) δ: 0.0 (s, 9H), 1.1 (br s, 1H), 2.01 (s, 2H), 3.76 (s, 2H), 7.1-7.3 (m, 5H).
