HCID 1816881,3,5-Triazinane-2,4-dione, 1,3,5-trimethyl-

Procedure

145 g (1 mol) of 1,3,5-trimethyl-biuret and 30 g of paraformaldehyde are heated together with 5 ml of concentrated hydrochloric acid 70° C for 5 hours. The liquid contents of the flask are then poured onto a dry metal sheet and, after solidification, the product is recrystallised from cyclohexane. This gives 145 g (98%) of 2,4-dioxo-hexahydro-1,3,5-trimethyl-s-triazine of melting point 88° to 90° C.
