Abstract
PURPOSE: To readily obtain the titled compound which is an intermediate for medicines from inexpensive raw materials in high yield, by reacting ethyleneimine as a starting raw material with a lower dialkyl ketone then with hydrogen sulfide and further reacting the resultant product with a furfuryl alcohol derivative.
CONSTITUTION: Ethyleneimine which is a starting raw material is reacted with a lower dialkyl ketone expressed by formula I (R1 and R2 are 1W4C alkyl) in a molar amount within the range of 0.5W1.5 times, preferably 0.9W1.0 based on the compound expressed by formula I at 0W50°C. The resultant product is subsequently reacted with hydrogen sulfide and then a furfuryl alcohol derivative expressed by formula II (R3 and R4 are 1W4C alkyl; R5 is H or acyl; ALK is 1W4C alkyl) at ambient temperature W 80°C to afford a compound expressed by formula III. Furthermore, the hydrogen sulfide is used in a amount within the range of 1W2 times based on the ethyleneimine and the compound expressed by formula II is used in a molar amount within the range of 0.5W2 times based on the ethyleneimine.
