Intermediates, 1-benzyl-2-substituted-3-carboxaldehyde[I]-[II], were prepared by the reaction of 2-substituted indole-3-carboxaldehyde with benzyl chloride. Indolylacrylophenone derivatives[III]-[X] were prepared from 1-benzyl-2-substituted-3-carboxaldehyde with acetophenone derivatives. They are as follows; 3-(1'-benzylindole-3'-yl)-1acrylophenone [III] 3-(1'-benzylindole-3-yl)-1(p-methoxy)acrylophenone [IV] 3-(1'-benzylindole-3-yl)-1(p-bromo)acrylophenone [V] 3-(1'-benzylindole-3-yl)-1(p-chloro)acrylophenone [VI] 3-(1'-benzyl-2'-methylindole-3'-yl)-1-acrylophenone [VII] 3-(1'-benzyl-2'-methylindole-3'-yl)-1-(p-methoxy)acrylophenone [VIII] 3-(1'-benzyl-2'-methylindole-3'-yl)-1-(p-bromo)acrylophenone [VIII] 3-(1'-benzyl-2'-methylindole-3'-yl)-1-(p-chloro)acrylophenone [X]
