Versuchsvorschrift

There was introduced into a solution of 28 g sodium acetate and 60 ml methanol 19 g of (2-furyl) (4-hydroxyphenyl) ketone (m.pt.=164° C.) prepared according to the method described in Example 1 (A) and (B), and then there was introduced dropwise 11 ml of bromine dissolved in 14 ml of acetic acid. After 2 hours stirring at ambient temperature, the mixture was poured into three volumes of water and the precipitate isolated. After recrystallisation in dichloroethane there was obtained 22 g of phenol dibromide melting at 164° C.
