실험 절차
58 g (340.027 mmol) of 2-chloro-5-fluoro-6-methylnicotinonitrile (preparation described in WO2007/41052, example U-2, page 80) was put in 1,2-ethanediol (580 ml) and then hydrazine hydrate (24.813 ml) and 56.091 ml (340.027 mmol) of diisopropyl ethylamine were added. The reaction mixture was heated with stirring for 16 h to 80° C. and then for 66 h to 120° C. After cooling, water (2.5 l) and ethyl acetate (2.5 l) were added and it was filtered with suction. The solid obtained was dried. 28.4 g (47% of theor.) of the target compound was obtained.
