Reaction Steps

In the same manner as described in example 3, starting from 2,10dicloro-8-fluoro-10,11dihydro-dibenzo[b,f]thiepin and N-methylpiperazine, there is obtained 1-[2-chloro-8-fluoro-10,11-dihydro-dibenzo[b,f]thiepin-10-yl]-4-methyl-piperazine which melts at 118°-120°. After recrystallisation of this base from ether and reaction with maleic acid the correponding maleate is obtained which melts at 174°-175°.
