Reaction Steps

To a sealed tube was added 5-bromo-2-fluoropyridine (1.25 g, 7.10 mmol) and cyclopropylamine (5.0 mL, 72 mmol). Upon heating at 80° C. for 48 hours the reaction was complete. The contents of the tube were transferred to a round bottom flask and concentrated in vacuo. The remaining residue was dissolved in dichloromethane and washed twice with saturated sodium bicarbonate and twice with brine. The organics were dried over sodium sulfate, filtered and concentrated in vacuo to afford the title compound (1.13 g, 75%) as a tan solid.
