Water → HCID 131723461、化合物

To a solution of methyl(3-(5-methoxy-3-pyridyloxy)propyl)amine (0.228 g, 1.16 mmol) in ethanol (4.3 mL) was added galactaric acid (122.0 mg, 0.58 mmol). Water (1.2 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) (1.4 mL). The filtrate was diluted with ethanol (6.5 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 141.2 mg (80.7%) of a white, crystalline solid, mp 140-141° C. The compound exhibits a Ki of 15 nM; the effect at muscle sites is 10 percent; and the effect at ganglia sites is 5 percent. The compound exhibits neurotransmitter release of 54 percent.
