Procedure
A solution of 19.68 g of 2,6-difluorophenylisothiocyanate and 34.1 g of N-{2-[N-(benzyloxy)amino]ethyl}phthalimide in 150 ml of benzene is heated to boiling under reflux for 6 hours. The cooled solution is separated from a slight precipitate and then evaporated in vacuo. The residual oil crystallizes from isopropyl ether. There is obtained 1-(benzyloxy)-3-(2,6-difluorophenyl)-1-(2-phthalimidoethyl)-2-thiourea of melting point 141°-143° (ether/methylene chloride).
