3 G. of the salt of racemic 3-{2-[4-(8-fluoro-10,11-dihydro-2-methyldibenzo[b,f]thiepin-10-yl)-1-piperazinyl]-ethyl}-2-oxazolidinone with (+)-camphor-10-sulfonic acid monohydrate [(S)-2-oxo-10-bornanesulfonic acid; α546 = +28.0° (water; c = 10%)] in the molar ratio of 1:2 are dissolved in 5 ml. of acetone and allowed to stand at room temperature for 2 hours. After the addition of 5 ml. of acetone, the entire mixture is allowed to stand for an additional 2 hours and then treated with 3 ml. of acetone. The solution is now left to stand at room temperature for 85 hours. The precipitate obtained is subsequently removed by filtration and washed with acetone, and 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 [that is, (+)-(S)-3-{ 2-[4-(8-fluoro-10,11-dihydro-2-methyl-dibenzo[b,f]thiepin- 10-yl)-1-piperazinyl]-ethyl}-2-oxazolidinone-(S)-2-oxo-10-bornanesulfonate (1:2)], from which the base is liberated by treatment with aqueous sodium hydroxide. The first crystallizate is obtained in a purity of about 84% and in a yield of 23.3% based on the racemate used (that is, 46.6% of theory). αD =+9.5° (chloroform; c =1%).
