Reaction Steps

5-{4-[(4-{Difluoro-[4-(5-hydroxypent-1-ynyl)phenyl]methoxy}-3-methylphenoxy)difluoromethyl]phenyl}pent-4-yn-1-ol is hydrogenated to completion on palladium/active carbon catalyst in THF. The catalyst is filtered off, and the filtrate is evaporated in vacuo, giving 5-{4-[(4-{difluoro-[4-(5-hydroxypentyl)phenyl]methoxy}-2-methylphenoxy)difluoromethyl]phenyl}-pentan-1-ol, which is sufficiently pure for further reactions.
