In a round-bottomed flask, (5-fluoropyridin-2-yl)methylamine dihydrochloride (800 mg, 4.0 mmol) was suspended in THF (15 ml). The suspension was cooled to 0° C. and triethylamine (1.75 ml, 12.6 mmol) was added followed by dropwise addition of acetyl chloride (0.30 ml, 4.22 mmol). After the addition was complete, the ice bath was removed and the reaction mixture was stirred at room temperature for 2 h. The reaction was quenched with water and extracted with EtOAc (2×). The combined organic layers were washed with water and brine then dried over sodium sulfate, filtered and concentrated to give 654 mg (97%) of N-(5-fluoro-pyridin-2-ylmethyl)-acetamide as a light brown oil which was used without further purification.
