Procedure

According to the procedure described in Example 1(c) for N-(8-oxo-4-oxa-1,7-diaza-tricyclo-[9.6.1.012,17]-octa-deca-11(18),12,14,16-tetraen-9S-yl)-3(R)-(3-phenyl-1H-pyrrol-1-yl)succinamic acid benzyl ester, 3(R)-t-butoxycarbonylamino-N-(2-hydroxy-1(S)-hydroxymethyl-2-methyl-propyl)succinamic acid benzyl ester was deprotected with trifluoroacetic acid. The crude amine salt and 3-biphenyl-4-yl-2,5-dimethoxy-tetrahydrofuran (prepared as described in Example 1(a)) were condensed in anhydrous 1,2-dichloroethane with trifluoroacetic acid to give in 11% yield 3(R)-[3-(biphenyl-4-yl)-1H-pyrrol-1-yl]-N-[2-hydroxy-1(S)-(hydroxymethyl)-2-methylpropyl]succinamic acid benzyl ester as an amorphous solid.
