実験手順

As described in Example 4(a) for the preparation of N-(1(S)-benzyl-2-hydroxyethyl)-3(R)-[3-(4′-cyano-biphenyl-4-yl)-1H-pyrrol-1-yl]succinamic acid benzyl ester, N-(1(S)-benzyl-2-hydroxyethyl)-3(R)-butoxycarbonyl-amino-succinamic acid benzyl ester (0.320 mmol) was deprotected. A solution of the resultant crude N-(1(S)-benzyl-2-hydroxyethyl)-3(R)-amino-succinamic acid benzyl ester trifluoroacetate salt and crude 3-(4′-carboxamidobiphenyl-4-yl)-2,5-dimethoxytetrahydrofuran (110 mg, 0.330 mmol) in 1,2-dichloroethane condensed in 18 hours to give a brown solid, which was purified via flash column chromatography with 5% MeOH/CH2Cl2 as eluant to provide 60 mg (31%) of N-(1-benzyl-2-hydroxyethyl)-3-[3-(4′-carbamoylbiphenyl-4-yl)-1H-pyrrol-1-yl]succinamic acid benzyl ester as a pale yellow solid, mp 192-4° C.
