4 g of 2-[(p-phenoxy)phenoxy]ethylamine and 11.2 g of chlorothioformic acid S-ethyl ester are dissolved in 150 ml of acetone. 14.5 g of potassium carbonate are added to the solution. This mixture is heated under reflux for 6 hours and then filtered. The residue is washed with acetone and the filtrate is evaporated in vacuo. The crystalline residue is suspended in cyclohexane and filtered to yield 2.5 g (53%) of 2-[(p-phenoxy)phenoxy]ethylthiocarbamic acid S-ethyl ester, m.p.--56°-58° C.
