Procedure
AAG154489 was synthesized as shown in Scheme 3. Compounds 10 was obtained by a Sonogashira coupling of 5a (from scheme 1) with (S)-2-[(5-bromo-furan-2-carbonyl)-amino]-pentanedioic acid diethyl ester 13. Compound 13 (Scheme 3) was synthesized by coupling the commercially available 5-bromo-2-furan-carboxylic acid 12 and L-glutamate diethyl ester hydrochloride in 72% yield. Hydrogenation and saponification of 10 afforded AAG154489.
