Procedure
As described in Example 1(c) for the preparation of N-(8-oxo-4-oxa-1,7-diaza-tricyclo-[9.6.1.012,17]-octadeca-11(18),12,14,16-tetraen-9-yl)-3-(3-phenyl-1H-pyrrol-1-yl)succinamic acid benzyl ester, 3(R)-amino-N-(1(S)-(N-methoxy-N-methylcarbamoyl)-3-methyl-butyl)succinamic acid benzyl ester was deprotected. 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 provide in 48% yield 3(R)-(3-biphenyl-4-yl-1H-pyrrol-1-yl)-N-[1(S)-(N-methoxy-N-methylcarbamoyl)-3-methyl-butyl]succinamic acid benzyl ester as an amorphous solid.
