Ethyl isothiocyanatoformate → N-ethoxycarbonyl-N'-n-butoxypropyl thiourea
Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Ethyl isothiocyanatoformate | HCID 85320 | — |
| Reactant | 1-Propanamine, 3-butoxy- | HCID 85461 | — |
| Solvent | Dichloromethane | HCID 6344 | — |
| Product | N-ethoxycarbonyl-N'-n-butoxypropyl thiourea | HCID 20207908 | — |
Reaction Steps
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.
