実験手順

7.5 ml (36 mmoles) of hexamethyldisilazane were added to a refluxing mixture of 3.06 g (0.03 mmole) of malonamide, 18.3 mg (0.1 mmole) of saccharin, 50 ml of ethyl acetate and 5 ml of pyridine and by titrating with 1 N sulfuric acid the ammonia evolved, it was found that 30 mmoles were expelled after refluxing for one hour. Volatile material was vacuum evaporated and the residue, which crystallized upon standing, was dried in vacuo to obtain 7.32 g (99%) of N,N'-bis-(trimethylsilyl)-malonamide melting at 72°-76° C. NMR Spectrum (CDCl3): Δ0.24 (s, 18H); 3.20 (s, 2H); 6.5 (broad, 2H).
