実験手順
5.1 parts by weight of methylisocyanate were added to a suspension of 10 parts by weight of ethoxycarbonylguanidine (manufactured according to Isr. J. Chem. 8, 651 [1970] ) in 60 parts by volume of anhydrous dioxane, in the course of which the temperature rose to 45°C and the precipitate dissolved. After a short time, a crystalline precipitate separated out again, which was filtered off after cooling and washed with ether. It was dried in vacuo over P2O5 and paraffin chips.
