Abstract

PURPOSE: To prepare the title compound in high purity and yield, with simple procedure, by reacting a morpholine hydrochloride with phosgene in an inert liquid medium.
CONSTITUTION: 4-Morpholinecarbonyl chloride is prepared by reacting morpholine hydrochloride with phosgene in an inert liquid medium such as toluene and xylene, at 50W150°C, pref. 60W120°C. The morpholine hydrochloride is prepared by dissolving 1 part by weight of morpholine in ≥4 parts of an inert liquid medium, and introducing a slightly excessive HCl into the solution under agitation. The morpholine hydrochloride thus prepared can be used to the above reaction without separation. Drawbacks of the conventional preparation process (low-temperature reaction, low yield, use of phosgene in large excess, etc.) are improved.
