N-(Trimethylsilyl)acetamide Chemical Properties,Uses,Production

Chemical Properties

WHITE TO YELLOWISH CRYSTALLINE MASS

Uses

N-Trimethylsilylacetamide is a silylating agent used in organic synthesis. N-Trimethylsilylacetamide is used in the preparation of the antibacterial agent Cefdinir (C242670).

Purification Methods

Distil the amide repeatedly in an inert atmosphere with all operations to be performed in an anhydrous atmosphere. In the presence of moisture, trimethylsilanol (b 31-34o/26mm) is formed and is a likely impurity (check by NMR). [Birkofer et al. Chem Ber 96 1473 1963, Beilstein 4 IV 4011.]
