実験手順
2.69 g of methyl cyanoacetimidate hydrochloride, 1.68 g of cyanamide and 5.0 g of molecular sieve (type 4A, 60 mesh through) were suspended in 30 ml of benzene and the suspension was made to react for 5 hours at 25°C under stirring. After reaction, insoluble materials were filtered off and then the filtrate was concentrated to dryness in vacuo to give 2.26 g of methyl N-cyanocyanoacetimidate (yield 91.2%) mp 45.5°C.
