Methyl isothiocyanate → HCID 15171119, compound
Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Methyl isothiocyanate | HCID 11167 | — |
| Reactant | 5-Amino-2-chloropyridine | HCID 79305 | — |
| Solvent | Acetonitrile | HCID 6342 | — |
| Product | HCID 15171119 | HCID 15171119 | 70.6% |
Reaction Steps
A mixture of 4.07g of 2-chloro-5-aminopyridine, 2.55g of methyl isothiocyanate and 30ml of acetonitrile was refluxed for 13.5 hours, to which 0.70g of additional methyl isothiocyanate was added and the mixture was refluxed for 3.5 hours. The reaction mixture was concentrated, and the residue was purified by a column chromatography [developing solvent: dichloromethaneethyl acetate (1: 1)] to afford 4.51g of 1-(6-chloro-3-pyridyl)-3-methylthiourea.
