Reaction Steps

This derivative was prepared from (1S)-4-amino-N-(5-amino-1-hydroxymethyl-pentyl)-3-chloro-N-isobutyl-benzenesulfonamide (XII) (example 44, step B) as described in general procedure B using (2S)-2-[(morpholine-4-carbonyl)-amino]-3-naphthalen-2-yl-propionic acid. The latter derivative was prepared from L-2-naphthylalanine as described for the preparation of (2S)-2-[(morpholine-4-carbonyl)-amino]-3-naphthalen-1-yl-propionic acid from L-1-naphthylalanine. The final product was obtained in 25% yield (51 mg).
