2-(3-Benzyloxycarbonylamino-5-benzyl-2-oxo-1,2-dihydro-1-pyridyl)-N-(1-benzyl-3,3,3-trifluoro-2-hydroxypropyl)acetamide was synthesized in the same manner as in Example 1. That is, 2-(3-benzyloxycarbonylamino-5-benzyl-2-oxo-1,2-dihydro-1-pyridyl)acetic acid (title compound in Reference Example 7, 380 mg, 0.968 mmol) was treated with 3-amino-1,1,1-trifluoro-4-phenyl-2-butanol (title compound in Reference Example 1, 249 mg, 1.14 mmol), WSCI hydrochloride (277 mg, 1.45 mmol) and HOBT (158 mg, 1.17 mmol) in DMF (10 mL) to give 428 mg (74%) of the target compound as a slightly yellow solid.
