As the starting substances, ethyl 4-chloro-2-phenoxycarbonylaminobenzoate and 4-(2-morpholinoethyloxy)benzenesulfonamide were used and the same method was applied as in Example 36 to obtain N-[4-(2-morpholinoethyloxy)benzenesulfonyl]-N'-(2-ethyloxycarbonyl-5-chlorophenyl)urea and further to obtain from 500 mg (0.98 mmol) of N-[4-(2-morpholinoethyloxy)benzenesulfonyl)-N'-(2-carboxyl-5-chlorophenyl)urea 120 mg of the above-identified compound (yield 27.2%). Properties: colorless crystal, Melting point: >200° C. (decomposition), PMR (δppm, DMSO-d6):2.48 (4H,t), 2.73 (2H,t), 3.57 (4H,t), 4.22 (2H,t), 7.12 (1H,s), 7.20 (3H,t), 7.85 (1H,d), 8.09 (2H,d), 11.56 (1H,br).
