摘要 The compound, prepared by this method, is familiar as tamoxifen hydrochloride and is applicable in medicine. The method is easily implemented in industrial conditions for preparation of a product of high purity and yield. Following the method,1-/4-(2-dimethylaminoethoxy)phenyl/-1,2-diphenyl-1-butene is heated in a medium of hydrochloric acid at a temperature between 50 and 55 degrees C for 5 to 9 hours.
