Procedure

In the same manner as in Example 1 (2), 5-cyano-3-methyl-2-benzofurancarboxylic acid (312 mg, 1.55 mmol) and t-butyl trans-(4-aminocyclohexyloxy)acetate (380 mg, 1.66 mmol) were condensed to give 534 mg of t-butyl trans-[4-[(5-cyano-3-methyl-2-benzofuranyl) carbonylamino]cyclohexyloxy]acetate as a colorless solid (84%).
