2-Methylcinnamic aldehyde → 1-(2-Benzyloxyphenyl)-3-methyl-4-phenylbutadiene

Participants

Reaction Steps

Following a procedure similar to that described in the first part of Preparation 3, 1.32 g of α-methylcinnamaldehyde, 4.47 g of 2-benzyloxybenzyltriphenylphosphonium chloride (prepared as described in Preparation 1) and 1.37 g of 1,8-diazabicyclo[5,4,0]-undec-7-ene were reacted in acetonitrile. The crude product thus obtained was purified as described in the first part of Preparation 3, to give 2.66 g (yield 90%) of 1-(2-benzyloxyphenyl)-3-methyl-4-phenylbutadiene as a colorless oil.
