Versuchsvorschrift

(R)-(-)-3'-(2-Amino-1-hydroxyethyl)-4'-fluoromethanesulfonanilide L-(+)-tartrate (2.0 g) was made into a free base using ion exchange resin (Dowex 50W X2) followed by treating with 20% ethanolic hydrochloric acid. The crystals which were separated out were collected to give 1.1 g of (R)-(-)-3'-(2-amino-1-hydroxyethyl)-4'-fluoromethanesulfonanilide hydrochloride, m.p. 189°-191° C.
