Furo[2,3-c]pyridin-5-ylmethanol (7.70 g, 51.63 mmol) is dissolved in pyridine (45 mL), treated with acetic anhydride (14.36 mL, 154.9 mmol) and stirred for 18 h at rt. The pyridine is removed in vaeuo and the resulting residue dissolved in EtOAc (200 mL), washed with 50% saturated sodium bicarbonate (4×90 mL), dried over MgSO4 and concentrated in vacuo to afford 9.32 g (94%) of furo[2,3-c]pyridin-5-ylmethyl acetate as a yellow oil. MS (EI) m/z: 191 (M+), 277, 148, 119, 118, 86, 84, 77, 63, 51, 50.
