Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Methyl isothiocyanate | HCID 11167 | — |
| Reactant | 1,1-Dimethyl-2-(3-pyridylmethyl)hydrazine | HCID 11148150 | — |
| Solvent | Toluene | HCID 1140 | — |
| Product | 1,1-Dimethyl-4-methyl-2-(3-pyridylmethyl)thiosemicarbazide | HCID 22450520 | 70.6% |
Reaction Steps
In 30 ml of toluene was dissolved 2.5 g of 1,1-dimethyl-2-(3-pyridylmethyl)hydrazine followed by addition of 1.2 g of methyl isothiocyanate and the mixture was refluxed for 1 hour. The reaction mixture was concentrated and the resulting crystals are collected by filtration, washed with ethyl ether and dried. The procedure gave 2.6 g of 1,1-dimethyl-4-methyl-2-(3-pyridylmethyl)thiosemicarbazide as white prisms.
