Upon stirring, the suspension was heated to 52 ° C. for 15 hours with vigorous stirring. Subsequently, it was cooled and alkalized by adding 4 parts of ice and 5 parts of concentrated ammonia. The reaction product was extracted with dichloromethane, and the organic layer was repeatedly washed with water. After removing the organic solvent under vacuum, 1- [4 '-(2-diethylaminoethoxy) phenyl] -trans-1- (3'-hydroxyphenyl) -2-phenyl-but-1-ene 95% [HPL
