Reaction Steps

2-[5-Benzyloxycarbonylamino-2-(3,5-dinitrophenyl)-6-oxo-1,6-dihydro-1-pyrimidyl]-N-(1-benzyl-3,3,3-trifluoro-2-hydroxypropyl)-acetamide was synthesized in the same manner as in Example 1. That is, [5-benzyloxycarbonylamino-2-(3,5-dinitrophenyl)-6-oxo-1,6-dihydro-1-pyrimidinyl]acetic acid (title compound in Reference Example 16, mixture with diethyl ether, 3.74 g, 7.08 mmol) was treated with 3-amino-1,1,1-trifluoro-4-phenyl-2-butanol (title compound in Reference Example 1, 1.78 g, 8.12 mmol), WSCI hydrochloride (1.63 g, 8.50 mmol) and HOBT (1.91 g, 14.1 mmol) in DMF (25 mL) to give 4.06 g (86%) of the target compound as a dark-brown solid.
