3-(2-Chloroethyl)-1,3-oxazolidin-2-one → 3-{2-[4-(8-Chloro-10,11-dihydro-2-methyl-dibenzo[b,f]thiepin-10-yl)-1-piperazinyl]-ethyl}-2-oxazolidinone

Reaction Steps

In a similar manner to that described in Example 1, from 1-(8-chloro-10,11-dihydro-2-methyl-dibenzo[b,f]thiepin-10-yl)-piperazine and N-(betachloroethyl)oxazolidinone, there is obtained 3-{2-[4-(8-chloro-10,11-dihydro-2-methyl-dibenzo[b,f]thiepin-10-yl)-1-piperazinyl]-ethyl}-2-oxazolidinone, which after recrystallization from ethyl acetate/petroleum ether, has a melting point of 184°-186°. The maleate salt melts after recrystallization from methanol/ether at 174°-175°.
