Reaction Steps

2-Chloro-5-nitropyridine (9.5 grams), 2,2,2-trifluoroethanol (6.0 grams), and lithium hydroxide (4.0 grams) were mixed in 50 ml. of DMSO and stirred overnight (about 18 hours) at room temperature. The reaction mixture was then poured into water and the product was separated by filtration. It was crystallized from ethyl acetate-hexanes, yield 5.0 grams, m.p., 35°-37° C.
