Again following the procedure of Example 1, to 1.31 parts of the ethoxycarbonyl isothiocyanate in 6 parts of methylene chloride are added 1.31 parts of butoxypropylamine. After 2 hours at room temperature, the methylene chloride is evaporated off. The viscous liquid product N-ethoxycarbonyl-N'-n-butoxypropyl thiourea (2.6 parts) gives the correct IR analysis.
