Procedure

1.0 g (2.93 mmol) of 3-benzyloxycarbonylamino-4-chlorobenzenesulfonamide and 1.18 g (2.93 mmol) of benzyl 4-chloro-2-N-phenoxycarbonylanthranilate were treated in the same way as Preparation Example 1 to obtain 1.43 g (yield 78%) of benzyl 2-{[(3-benzyloxycarbonylamino-4-chlorobenzene sulfonylamino)carbonyl]amino}-4-chlorobenzoate. Properties: colorless amorphous, PMR (δ ppm, DMSO-d6): 5.19 (2H, s), 5.36 (2H, s), 7.21 (1H, dd), 7.34-7.48 (10H, m), 7.72-7.76 (2H, m), 7.97 (1H, d), 8.25 (1H, d), 8.30 (1H, d), 9.53 (1H, s), 10.30 (1H, s). 1.38 g (2.20 mmol) thereof was dissolved in 50 ml of THF, then 200 mg of palladium-carbon (10%) was added and the mixture was stirred under a hydrogen flow for 2 hours. The reaction mixture was filtered with Celite to remove the palladium-carbon, then the filtrate was concentrated in vacuo to obtain a carboxylic acid. The product obtained was suspended in 50 ml of THF, then 356 mg (2.20 mmol) of CDI was added under ice cooling and the resultant mixture was treated in the same way as Preparation Example 1 to obtain 560 mg (yield 66%: 2 steps) of the above-identified compound. Properties: colorless crystal, Melting point: >200° C. (decomposition), PMR (δ ppm, DMSO-d6): 6.00 (2H, s), 7.12 (1H, s), 7.26 (2H, t), 7.48 (1H, d), 7.66 (1H, s), 7.86 (1H, d), 11.76 (1H, br).
