Water → HCID 12112223、化合物

To a solution of methyl(3-(5-isopropoxy-3-pyridyloxy)propyl)amine (0.643 g, 2.87 mmol) in ethanol (10.7 mL) was added galactaric acid (302.0 mg, 1.44 mmol). Water (3.0 mL) was added drop-wise, while warming the solution to near reflux. To remove some white, insoluble crystals, the warm solution was filtered through a glass wool plug, washing the filter plug with a warm solution of ethanol-water (4:1, v/v) (3.4 mL). The filtrate was diluted with ethanol (16 mL), producing a white precipitate. The mixture was allowed to cool to ambient temperature and was further cooled at 5° C. for 48 h. The precipitate was filtered, washed with ethanol (10 mL), and vacuum dried at 40° C. for 24 h to give 251.1 mg (53.2%) of a white, crystalline solid, mp 118-120° C. The compound exhibits a Ki of 21 nM; the effect at muscle sites is 22 percent; and the effect at ganglia sites is 0 percent. The compound exhibits neurotransmitter release of 36 percent.
