Versuchsvorschrift
The mixture of 5-fluoro-pyridine-2-carbonitrile (0.16 g, 1.27 mmol) and Pd/C (0.030 g, 10% wt) in 15 ml of MeOH and 0.50 ml of concentrated HCl was placed under H2 which was provided by a balloon and stirred at RT for 4 h, filtered through Celite®, condensed, the residue was purified by flash column chromatography. The titled compound was obtained as a light yellowish solid. MS (ES+): 127.2 (free base)(M+H)+. Calc'd for C6H7FN2 (free base)—126.13.
