How it is made

E. F. Godefroi et al., German patent 2,063,857 corresponds to US patent 3,658,813 (1971, 1972 both to Janssen)

Alpha,2,4-Trichloroacetophenone + imidazole + allyl chloride (amine formation/carbonyl reduction/ether formation).

By bromination of 2',4'-dichloroacetophenone, followed by reduction with sodium borohydride to form an epoxide intermediate. The epoxide is opened with imidazole, and the resulting alcohol is then etherified.
