Reaction Steps

4.72 g (0.02 mole) 1-hydroxy-1-phenyl-3-(1,2,3-thiadiazole-5-yl)-urea were suspended in 40 ml tetrahydrafuran and then reacted with 1.19 ml (0.02 mole) methylisocyanate. After addition of 3 drops of triethylamine there is obtained a clear solution and after a further 10 minutes crystals already begin to separate out. The reaction mixture is allowed to stand at room temperature. Thereafter the crystals are separated off and digested with diisopropylether.
