Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Thionyl Chloride | HCID 24386 | — |
| Reactant | 2-Fluoronicotinic acid | HCID 96089 | — |
| Product | 2-Fluoropyridine-3-carbonyl chloride | HCID 21959582 | — |
Reaction Steps
2-Fluoropyridine-3-carboxylic acid (7 g, Step C) was suspended in SOCl2 (100 mL). After heating under reflux for 2 h, the mixture became homogeneous. Excess SOCl2 was removed in vacuo to afford a brown solid as desired product.
