実験手順
1.00 g (5.23 mmol) 6-cyclopropyl-pyridine-2-carboxylic acid ethyl ester was suspended in 10 mL THF and treated with 350 mg (14.6 mmol) LiOH and 5 mL water at RT for 2.5 h. The reaction mixture was acidified with 4 M aqueous hydrochlorid acid and extracted with EtOAc. The combined organic phases were dried over sodium sulfate, filtered and concentrated in vacuo.
