    摘要: The present invention provides herein a two-step process for preparing pharmaceutically pure quetiapine and salts thereof by obtaining the starting material 11-chloro-dibenzo-thiazepine followed by reacting the 11-chloro-dibenzo-thiazepine with 1-(2-hydroxyethoxy)ethylpiperazine, or its salt, in the presence of an inorganic or organic base in an organic solvent or in a two-phase solvent system. The present invention provides also a novel, one-pot reaction process for preparing pharmaceutically pure quetiapine and salts thereof. The two processes provided herein can be easily, conveniently and inexpensively scaled-up.
