Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | 4-Iodobenzamide | HCID 77561 | — |
| Reactant | Lawesson's reagent | HCID 87949 | — |
| Solvent | Tetrahydrofuran | HCID 8028 | — |
| Product | HCID 23279242 | HCID 23279242 | 134.5% |
Reaction Steps
A mixture of 2.1 g of 4-iodobenzamide, 30 ml of tetrahydrofuran, and 2 g of Lawesson's reagent was heated to reflux for 1 hour. It was partitioned between toluene and 10% aqueous sodium carbonate solution. The organic phase was dried and evaporated. The crude product was passed over a plug of silica gel using acetone/hexane 1:1 for elution. Crystallization from methylene chloride/hexane gave 1.75 g of yellow crystals with m.p. 163-165° C.
