Reaction Steps

A solution of bis(4-fluorophenyl)diazomethane, prepared as above from the action of activated manganese dioxide (32.3 g) on 4,4'-difluorobenzophenone hydrazone (23.2 g) in dichloromethane (105 mL), was added to a solution of methacrolein (12.5 mL) in heptane (100 mL). The mixture was heated at 40° C. for 6 hours then the amber colored solution was evaporated in vacuo. The resulting solid was triturated with hexane (100 mL) to give 22.0 g of 2,2-bis(4-fluorophenyl)-1-methylcyclopropanecarboxaldehyde, mp 110°-113° C. Recrystallization of a sample from hexane provide the analytical specimen, mp 111°-113° C.
