반응 단계
In analogy to Example 45, by reacting [1-(2,2-dimethyl-1,3-benzodithiol-5-yl)ethyl]triphenylphosphonium bromide with ethyl 4-formylphenyl carbonate, there was obtained ethyl p-[(E)-2-(2,2-dimethyl-1,3-benzodithiol-5-yl)propenyl]phenyl carbonate, melting point 93°-94° C. Hydrolysis of this compound with aqueous potassium hydroxide in ethanol gave p-[(E)-2-(2,2-dimethyl-1,3-benzodithiol-5-yl)propenyl]phenol, melting point 123°-124° C.
