In a device shown in FIG. 2, 38.5 kg/hr of aqueous 36 wt% hydrochloric acid solution was fed through a conduit 2 and 13.0 kg/hr of 5-(dimethylamino)methylfurfuryl alcohol was fed through a conduit 3 to a reactor 1 maintained at a temperature of 20° to 30° C. Aqueous hydrochloric acid solution of 5-(dimethylamino)methylfurfuryl alcohol hydrochloride thus obtained was continuously fed to a reactor 5 through a conduit 4. Under maintaining a temperature of the reactor at 50° to 60° C., 13.3 kg/hr of an aqueous 75 wt% cysteamine hydrochloride solution was continuously fed to the reactor 5 through a conduit 6. Further, a reaction product was continuously discharged from the reactor 5 through a conduit 7. Residence time at the reactor 1 was 10 minutes and the residence time at the reactor was 30 minutes.
