Versuchsvorschrift

The pyrazole acid, prepared by coupling methyl ester 85 (Procedure 26) with 2-chlorobenzoyl chloride (21) followed by hydrolysis and bromination as shown in Procedure 8, was coupled to amine 169 (Procedure 34) using the method of Procedure 10. Formation of the amidine using the method of Procedure 33 using ethylene diamine afforded the title compound.
