A mixture of 3.3 g of 3-chloro-1,2-dihydroxy-n-propane and 8 g of n-propylamine is allowed to stand at room temperature for 5 days. The reaction mixture is condensed to dryness under reduced pressure, whereby 5.0 g of N-n-propyl-2,3-dihydroxy-n-propylamine hydrochloride are obtained as a crude product. 5.0 g of said crude product and 3 g of triethylamine are dissolved in 40 ml of methanol. 3.2 g of 2-chloroethyl isocyanate are added to the solution at 0° to 5° C. Then, the reaction mixture is treated in the same manner as described in Example 62-(1). 3.0 g of 1-(2-chloroethyl)-3-n-propyl-3-(2,3-dihydroxy-n-propyl)urea are obtained as a colorless oil.
