Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Lithium Hydroxide | HCID 3939 | — |
| Reactant | Ethyl 6-phenylnicotinate | HCID 11096332 | — |

| Product | 6-Phenylnicotinic acid | HCID 120118 | 81.9% |
Reaction Steps
LiOH (38 mg, 0.93 mmol) was added to a stirred solution of 6-phenyl-nicotinic acid ethyl ester (140 mg, 0.62 mmol) in THF:MeOH:H2O (3:1:1, 2.8 mL), and the resulting mixture was stirred at room temperature overnight. The methanol and THF were evaporated from the reaction mixture, which was then diluted with water (2 mL), acidified with citric acid solution and the product was extracted with EtOAc. The organic layer was washed with saturated brine solution, dried over Na2SO4 and concentrated in vacuo to afford 100 mg (81.9% yield) of 6-phenyl-nicotinic acid (100 mg). LCMS purity: 98.1%.
