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: To a solution of 30 g of morpholine acetonitrile in 75 ml of ethyl acetate was added 22.5 ml of dimethyl sulfate, corresponding to approximately equivalent molar amounts of the two reagents. The resulting solution was mechanically stirred in an oil bath maintained at 40° C. After 10 minutes of stirring, a semi-solid precipitate having a brownish coloration formed and settled on the bottom of the flask. HPLC (high pressure liquid chromatography) analysis showed at least 4 undesirable side products, which were removed. The remaining solution was again heated to 40° C. and reacted for an additional 16 hours. After this time, the resulting white paste was filtered and washed with ethyl acetate. MMA was isolated after drying this filtrate as a free flowing off-white solid in 79% yield, having a melting point of 99-101° C. The purity of the MMA was determined by HPLC to be greater than 95%. After 10 minutes of stirring formed were removed The remaining solution was again heated to 40° C. reacted for an additional 16 hours After this time, the resulting white paste was filtered washed with ethyl acetate MMA was isolated after drying this filtrate as
