Molar excess (5 milliliters) of thionyl chloride was added to a solution of the 3-methylthio-5H-dibenzo[a,d]cyclohepten-5-ol intermediate in 45 milliliters of benzene and the resulting mixture heated under reflux for two hours to obtain a 5-chloro-3-methylthio-5H-dibenzo[a,d]cycloheptene (chloro compound) intermediate in the reaction mixture. The reaction mixture was subjected to reduced pressure to co-evaporate benzene and unreacted thionyl chloride, and the procedure repeated with several additions of benzene to obtain a purified chloro compound intermediate.
