Reaction Steps

A mixture of 13.6 parts of 2-bromo-1-(2,4-dichlorophenyl)-1-ethanone, 13.1 parts of 3-(2-naphtalenyloxy)-1,2-propanediol, 3 parts of 4-methylbenzenesulfonic acid, 180 parts of benzene and 80 parts of butanol is stirred and refluxed for 12 hours with water-separator. The reaction mixture is evaporated and the residue is triturated in methanol. The product is filtered off and crystallized from 2-propanol, yielding A 2-(bromomethyl)-2-(2,4-dichlorophenyl)-4-[(2-naphthalenyloxy)methyl]-1,3-dioxo-lane; mp. 117.6° C.
