Participants

Reaction Steps

To a stirred mixture of 4-(4-methoxyphenyl)-2-butanone (15.4 g.), benzoyl chloride (13 g.) and methylene chloride (250 ml) at 0° C was added portionwise aluminium chloride (23 g.) over a 20 minute period. The mixture was stirred a further 1 hour at room temperature and then poured onto ice and worked up in the usual way.
