1-Butanol → 2-(Bromomethyl)-4-(4-chloro-1-naphthalenyloxymethyl)-2-(2,4-dichlorophenyl)-1,3-dioxolane

Participants

Reaction Steps

A mixture of 13.6 parts of 2-bromo-1-(2,4-dichlorophenyl)-1-ethanone, 15.2 parts of 3-(4-chloro-1-naphthalenyloxy)-1,2-propanediol, 3 parts of 4-methylbenzenesulfonic acid, 80 parts of butanol and 180 parts of benzene is stirred and refluxed for 24 hours with water-separator. The reaction mixture is evaporated and the residue is triturated in 2-propanol. The product is filtered off and crystallized from butanol, yielding A+B 2-(bromomethyl)-4-(4-chloro-1-naphthalenyloxymethyl)-2-(2,4-dichlorophenyl)-1,3-dioxolane; mp. 122.7° C.
