実験手順

To a suspension of (2E)-1-[6-(2,5-dimethyl-1H-pyrrol-1-yl)pyridin-3-yl]-3-(2-hydroxyphenyl)prop-2-en-1-one (0.31 g, 0.97 mmol) in EtOH (8.5 mL) was added hydrazine hydrate (65% solution, 0.146 mL, 1.95 mmol). After stirring for 15 min, the reaction mixture was concentrated to give 2-{3-[6-(2,5-dimethyl-1H-pyrrol-1-yl)pyridin-3-yl]-4,5-dihydro-1H-pyrazol-5-yl}phenol as a yellow solid (0.32 g, 99%). LCMS: (FA) ES+ 333.2 (M+1).
