(Trimethylsilyl)methylamine Usage And Synthesis

Purification Methods

A possible contaminant is hexamethyldisiloxane. It should have two 1H NMR signals in CDCl3; if not, dissolve it in *C6H6, shake it with 15% aqueous KOH, separate, dry (Na2SO4), filter, evaporate and distil it using a still of ca 10 theoretical plates. The water azeotrope has b 83o/735mm; hence it is important to dry the extract well. The hydrochloride has m 198-199o (from MeOH or Me2CO). [Noll et al. J Am Chem Soc 73 3867 1951, Beilstein 4 IV 3878.]
