Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Dimethylformamide | HCID 6228 | — |
| Reactant | Thionyl Chloride | HCID 24386 | — |
| Reactant | 5-Bromonicotinic acid | HCID 88707 | — |

Reaction Steps
To a mixture of 5-bromonicotinic acid (10 g) in thionyl chloride (25 ml) was added anhydrous DMF (0.5 ml). The whole was heated to reflux for overnight. After cooled to RT, the excess thionyl chloride was removed under reduced pressure. A white solid 5 (11 g) was obtained, which was used for the next step without further purification.
