The downstream synthesis method of this compound is introduced below.
To a solution of 4-fluorophenol (224 mg, 2.0 mmol) in DMF (5.0 mL) was added sodium hydride (48 mg, 2.0 mmol) at room temperature. After stirring for 10 min, methyl 2-chloro-5-iodonicotinate (J. Org. Chem. 1989, 54, 3618-3624, 594 mg, 2.0 mmol) was added to the reaction mixture. The reaction mixture was stirred under reflux for 16 h. Then the reaction mixture was poured into water (50 mL) and extracted with ether (50 mL x 3). The combined organic extracts were washed with brIne (50 m(at)-) and dr*(at)–d, (sod.uTY: s.1l(at)a(at)e).
