Procedure

To the solution of 4-[N-[1-[N-(benzofuran-2-ylcarbonyl)amino]cyclohexanecarbonyl]amino]-3-piperidinol hydrochloride (6.0 g) obtained in Step 2 of Example 1 in 50 ml of ethanol, were added 3.7 ml of 2-fluoronitrobenzene and 4.8 ml of triethylamine. The reaction mixture was refluxed overnight and concentrated. The resulting residue was filtered and dried to give 7.2 g of the titled compound.
