Reaction Steps

Lithium hydroxide (469 mg, 19.6 mmol) is added to a solution of methyl 5-(2,2,3,3-tetrafluoropropoxyl)pyridine-2-carboxylate (1.047 mg, 3.92 mmol) in THF (7 mL) and water (7 mL). The reaction mixture is stirred for 1 hour at 60° C., cooled to ambient temperature, quenched with 1 M HCl (20 mL), diluted with brine and extracted with dichloromethane (3 times). The organic layers are combined, dried over MgSO4, filtered, and concentrated under reduced pressure to give the title compound (921 mg, 93%). ES/MS (m/e): 254.0 (M+1).
