Versuchsvorschrift

The foregoing precedure is repeated using 100 g. of racemic 3-{2-[4-(8-fluoro-10,11-dihydro-2-methyl-dibenzo[b,f]thiepin-10-yl)-1-piperazinyl]-ethyl }-2-oxazolidinone, 113.2 g. of (+)-camphor-10-sulfonic acid monohydrate and 300 ml. of acetone. The stirring under reflux is carried out for 24 hours in place of 72 hours, and the drying under reduced pressure is prolonged. Whereupon, there is obtained the di-(camphor-10-sulfonic acid) salt of (+)-(S)-3-{2-[4-(8-fluoro-10,11-dihydro-2-methyl-dibenzo[b,f]thiepin-10-yl)-1-piperazinyl]-ethyl}-2-oxazolidinone; αD =+14.9°, α364 =+104.0° (chloroform; c = 3.0%); melting point 174°-175° C. (after recrystallization from acetone).
