Reaction Steps
Crude (R)-(-)-3'-(2-amino-1-hydroxyethyl)-4'-fluoromethanesulfonanilide (15.8 g) and 9.6 g of L-(+)-tartaric acid were dissolved in water, ethanol was added thereto and the crystals separated out thereby were collected and repeatedly recrystallized from water-ethanol to give 16 g of (R)-(-)-3'-(2-amino-1-hydroxyethyl)-4'-fluoromethanesulfonanilide L-(+)-tartrate. M.p. 91°-92 ° C.
