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). | [General Description]
The efficiency of N-(Trimethylsilyl)acetamide (TMS acetamide) as allyl group scavenger and its compatibility with Fluorenylmethyloxycarbonyl chloride (Fmoc) protecting groups were studied. | [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.] |
