Reaction Steps

Diphenyl ether (175 ml) was heated to reflux temperature, and Intermediate 10 was gradually added down an air condenser. Once all the reagent had been added the mixture was heated under reflux for a further 30 min. The mixture was then cooled and 2-methylpentane (200 ml) was added. The solid formed was collected by filtration to give the title compound (24.6 g).
