实验步骤: A reaction mixture was prepared from 203 ml. each of triethylamine and pyridine plus 63 g. of morpholinoacetonitrile. Hydrogen sulfide was bubbled through the heated, stirred reaction mixture for about 2.5 hours. Stirring was continued overnight at ambient temperature. The next day, H2S was passed through the heated, stirred reaction mixture for an additional 1.5 hours. At this point, the solvents were evaporated in vacuo and the residue triturated with ether. The ether was discarded and the residue dissolved in ethanol. Crystalline morpholinothioacetamide formed in the above reaction precipitated and was separated by filtration. Treatment of the filtrate with alcoholic hydrogen chloride yielded morpholinothioacetamide hydrochloride melting in the range 64°-80° C. See also J.A.C.S., 72, 2804 (1950).

实验步骤: 2-Morpholin-4-ylethanethioamide (0.403 g, 2.52 mmol), 1,3-dichloroacetone (0.353 g, 2.77 mmol) and sodium bicarbonate (0.234 g, 2.77 mmol) was stirred in 1,2-dichloroethane (4 mL) at room temperature for 74 h at which point 1,4-dioxane was added in an attempt to improve solubility and the mixture was stirred for a further 30 h. The reaction mixture was filtered and the filter cake was washed with 1,2-dichloroethane. The filtrate was added dropwise to a cooled (ice bath) solution of thionyl chloride (0.202 mL, 2.77 mmol) in 1,2-dichloroethane (3 mL). The solution was stirred at 70° C. for 0.5 h and then cooled to room temperature. The brown mixture was filtered and washed with 1,2-dichloroethane to afford 4-{[4-(chloromethyl)-1,3-thiazol-2-yl]methyl}morpholine hydrochloride as a very pale brown solid (0.024 g, 0.091 mmol, 4% yield). 1H NMR (400 MHz; D2O): 3.29-3.39 (m, 4H); 3.78-3.92 (m, 4H); 4.63 (s, 2H); 4.67 (s, 2H); 7.67 (s, 1H); MS (EI) for C9H13ClN2OS: 233 (MH+) was added in an attempt The reaction mixture was filtered the filter cake was washed with 1,2-dichloroethane The filtrate was added dropwise to The solution was stirred at 70° C. for 0.5 h The brown mixture was filtered washed with 1,2-dichloroethane
