Reaction Steps

2-Fluoro-5-trifluoromethylpyridine (1.831 g, 11 mmol) was dissolved in anhydrous THF (15 mL) with stirring under nitrogen and cooled to 0° C. in an ice bath. To this was added dropwise over 30 minutes a solution of 3-amino-1-propanol (0.76 mL, 10 mmol) in anhydrous THF (15 mL) and 1M potassium tert-butoxide in THF (10 mL, 10 mmol). The yellow solution was allowed to stir and slowly warm to room temperature overnight. The reaction mixture was poured into water (75 mL) and extracted with ether (2×50 mL). The organic phase was washed with brine (50 mL), dried (Na2SO4), filtered and evaporated under vacuum to a yellow liquid, which was nearly pure by NMR and MS, and was used as such without further purification.
