関与物質

反応手順

A solution of pyridin-3-yl-acetic acid hydrochloride (10 g, 57.6 mmol) in MeOH (30 mL) was treated with thionyl chloride (4.2 mL, 57.6 mmol) and the mixture was stirred at room temperature for 2 h. Solvent was removed in vacuo and the residue was partitioned between saturated aqueous NaHCO3 and EtOAc. The organic phase was collected, dried over MgSO4 and evaporated to give the title compound (7.9 g) as a colourless oil. 1H NMR (CDCl3): 8.53 (2H, m), 7.64 (1H, d), 7.33-7.20 (1H, m), 3.72 (3H, s), 3.64 (2H, s).
