反応手順

Under nitrogen gas, 150 mL fresh ethanol was added to the free base of metformin in ethanol, and to the free base of metformin in ethanol was slowly added 42 g (0.095 eq.) folacin solid. At that time the temperature of the reaction mixture began to ascend. The reaction was stirred and the adding speed was controlled to keep the reaction temperature not exceeding 50° C. Stirring was continued until the solid was substantially dissolved. When new solid began to present, ⅔-⅘ volume of solvent was removed under reduced pressure, and the reaction was cooled to ambient temperature to give the crude product of folacin-metformin compound.
