Reaction Steps

A solution of 90 gm of 4-nitro-phenacyl acetate and 33.9 gm of 1-cyano-guanidine in 200 ml of dioxane and 20 ml of 5N hydrochloric acid was stirred for 2 days at room temperature. A first crop of the product was filtered off; the solution, after the addition of another 40 ml of 5N hydrochloric acid, was stirred for 3 days and furnished a second crop of the product. The total yield of the title compound was 46 gm, m.p. >285° C.
