Procedure

2.50 g of (1R,2S)-2-carboxymethylamino-1,2-diphenylethanol mono sodium salt was dissolved in 60 ml of water and 1.2 M hydrochloric acid was added to adjust the pH at 8. The precipitated crystals were washed 2 times with water and 2 times with methanol. The washed crystals were dried under reduced pressure (about 2 mm Hg) at 70 ° C. for 12 h. Yield 1.95 g (84%); mp 249°-251° C. (decomp.); [α]D21 +3.3 (c 1.00, lM NaOH). IR (KBr): 3320, 3050, 2890, 1625, 1570, 1390, 760, 710, 700 cm-1 (the spectum is identical with that of (1S,2R)-form).
