Reaction Steps

18 g of 1-p-tolylaminocyclohexanecarbonitrile are dissolved in 90 ml of acetic acid in a 250 ml three-necked flask, at room temperature and under nitrogen, the mixture is heated to 35° C., 8.74 g of NaOCN are then added portionwise, heating is continued up to 60° C. and the mixture is stirred for 2 hours. 29 ml of 12N HCl and then 19 ml of water are introduced into the reaction medium, which is then heated for 30 minutes from 50 to 90° C. The reaction medium is transferred into about 1 l of water and a white precipitate forms, which is recovered by filtration and then dried. The product 1-p-tolyl-1,3-diazaspiro[4.5]decane-2,4-dione is obtained in the form of a white solid.
