Reaction Steps

38.8 G. of 3,10-dichloro-10,11-dihydro-8-fluoro-dibenzo[b,f]thiepin into 100 ml. of chloroform are heated with 82 g. of 1-carbethoxypiperazine for 24 hours under reflux conditions. The reaction mixture is poured on ice water and equilibrated with chloroform. The organic phase is dried over magnesium sulfate and evaporated under reduced pressure. Raw 1-carbethoxy-4-(3-chloro-10,11-dihydro-8-fluoro-dibenzo[b,f]thiepin-10-yl)-piperazine is obtained as a yellow oil.
