Versuchsvorschrift

The procedure is repeated in all essential details, except 4-hydroxy-5-chloropentanoic acid is substituted for β-chlorolactic acid and isopropylamine is substituted for 3,4-dimethoxyphenethylamine to produce the intermediate 5-isopropylamino-4-hydroxypentanoic acid. The hydroxy and amino groups are protected as described in Example I. The resulting acid is reacted with 1-naphthol instead of phenol and the protecting groups are removed as in Example I. The resulting compound should be a short acting β-blocker.
