실험 절차

To a solution of (S)-3-amino-1-(1-(3-chloro-5-(trifluoromethyl)pyridin-2-yl)piperidin-4-yl)pyrrolidin-2-one (0.15 g, 0.41 mmol) in DMF (10 mL) was added N-ethyl-N-isopropylpropan-2-amine (0.160 g, 1.24 mmol) and 6-chloropyridazine-3-carbonitrile (0.173 g, 1.24 mmol) and the reaction was heated to 90° C. overnight. The reaction was diluted with EtOAc (150 mL) and washed with water (100 mL), and brine (10 mL), dried over MgSO4, filtered and concentrated under vacuum. The material was purified on silica, using 1:1 EtOAc:DCM as eluent to yield a solid, which was further triturated with diethyl ether to yield (S)-6-(1-(1-(3-chloro-5-(trifluoromethyl)pyridin-2-yl)piperidin-4-yl)-2-oxopyrrolidin-3-ylamino)pyridazine-3-carbonitrile (0.028 g, 0.060 mmol, 14% yield). Mass spectrum (apci) m/z=466.0, 467.9 (M+H).
