반응 단계
The benzoin starting material can be prepared by adding bromine (18.1g) dropwise to a stirred solution of 4,4'-dichlorodeoxybenzoin (30g) in dry diethylether (400ml). The solution is stirred for a further hour and evaporated to provide crude α-bromo-4,4'-dichlorodeoxybenzoin (40g) which when recrystallised from methanol has a melting point of 81°-83°.
