Reaktionsschritte

A mixture of 3-chloro-2-cyano-5-trifluoromethylpyridine (5.1 g) and 5% palladium on charcoal (5.1 mg as Pd metal) was stirred at 20° C. with methanol and concentrated hydrochloric acid (2.5 ml) under 1 atmosphere of hydrogen. After 4 hours the reaction was judged to be complete by hplc. The mixture was filtered through Celatom, washed with methanol and water and evaporated to give 2-aminomethyl-3-chloro-5-trifluoromethylpyridine hydrochloride in 95-97% yield, NMR (in D2O) 4.6 (s, 2H), 8.35 (s, 1H), 8.9 (s, 1H).
