반응 단계
3-Fluoro-isonicotinic acid (50 mg, 0.354 mmol) and p-anisidine (44 mg, 0.354 mmol) was added to 2 ml dry THF and the mixture was cooled to −78° C. LiHMDS (1M in THF, 1.24 ml) was added and the mixture was allowed to warm to room temperature over night. Hydrochloric acid (1M in methanol, 5 ml) was added and the volatiles were removed in vacuo. The crude material was purified by preparative RP chromatography to give 11 mg (45 μmol; 13% yield) of pure desired product. LC-MS (method V): rt=1.82 min; m/z [M+H]+ 245.
