Versuchsvorschrift

A solution of (R)-mandelic acid (88 mg) and (S)-5,11-dihydro-5-[1-(4-methoxyphenethyl)-2-pyrrolidinylmethyl]dibenzo[b,e][1,4]thiazepine (see Examples 1 and 6) (250 mg) in dichloromethane (10 ml) was stirred at room temperature for 16 hours and evaporated under reduced pressure. The residue was triturated with ether and the resulting solid collected, dried and recrystallised from ethyl acetate/hexane to give the title compound as colourless crystals, (250 mg, 83%), m.p. 151°-153° C., [α]58925 -70.4° (c=0.575 in ethanol).
