Dimethylamine → Urea, N,N-dimethyl-N'-(4-(4-morpholinyl)-6-propyl-1,3,5-triazin-2-yl)-

Participants

Reaction Steps

A gaseous stream of dimethylamine is passed through a solution of 5 g (0.0145 mole) of phenyl (4-morpholino-6-propyl-1,3,5-triazin-2-yl)carbamate (compound 28 prepared in example 3) in 100 ml of anhydrous dichloromethane for three hours at a temperature of 20° C. The mixture is then allowed to stand for 12 hours. It is washed successively with a dilute sodium hydroxide solution and with water. The organic phase is dried over sodium sulfate and the solvent is evaporated under reduced pressure. The residue obtained crystallizes in a 50:50mixture (v/v) of ethyl acetate-hexane. 1.7 g of N,N-dimethyl-N'-(4-morpholino-6-propyl-1,3,5-triazin-2-yl)-urea is obtained.
