Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Ethanol | HCID 702 | — |
| Reactant | Thionyl Chloride | HCID 24386 | — |
| Reactant | 2-Chloronicotinic acid | HCID 76258 | — |
| Product | Ethyl chloronicotinate | HCID 2796614 | — |
Reaction Steps
To a solution 2-Chloro-nicotinic acid (12.5 g) in Ethanol (250 ml) was added thionyl chloride (5.77 ml) dropwise and refluxed for 1.5 hours. The mixture was concentrated to remove ethanol and diluted with 300 ml water. Solid sodium bicarbonate was added to adjust the solution to pH 8.0. This was extracted with ethyl acetate, washed with water, saturated bicarbonate solution, water and brine, dried over Na2SO4, filtered and concentrated to a yellow liquid (10.0 g). MW 185.61; MS (m/e) 185 (M+).
