43.4 g. (0.2 mole) of O-ethyl N,N-diisobutyl-thiocarbamate are introduced into a 100 ml. round-bottomed flask, and 2.5 g. of diethyl sulfate are added. The mixture is refluxed for 90 minutes on an oil bath heated to 160°C, and thereafter the product is isolated by vacuum distillation. 39.8 g. (92 %) of S-ethyl N,N-diisobutyl-thiocarbamate are obtained; b.p.: 137°-138°C/20 Hgmm., nD25 = 1.4689.
