実験手順

To a solution of methyl 6-methoxynicotinate (Avacado), 0.1 g (0.6 mmol) in 5 mL of tetrahydrofuran was added a solution of 1.2 mL of 5 N sodium hydroxide in 5 mL of water. The mixture was stirred for four hours at ambient temperature, acidified to pH=3 with 5 N HCl and concentrated to dryness to yield the crude desired compound. MS (ion spray) 154.0 (M+1). The crude product was carried on without further purification.
