The Grignard reaction of dibenzo[a,d]cyclohepta-1,4,6-triene-5-one (I) with allyl magnesium bromide (A) in ethyl ether gives 5-hydroxy-5-allyldibenzo[a,d]cyclohepta-1,4,6-triene (II), which is dehydrated with acetic anhydride and acetyl chloride at 90 C yielding 5-propenylidenedibenzo[a,d]cyclohepta-1,4,6-triene (III). Finally, this compound is treated with phenylmagnesium bromide and dimethylamine (B) at 80 C.
