Participants

Reaction Steps

Thionyl chloride (10 ml) was added to 5.0 g (19.5 mmol) of 4-(4-n-propyloxyphenyl)benzoic acid synthesized in the step (ii), and the mixture was refluxed overnight. After an excess amount of thionyl chloride was removed from the resultant mixture, 4′-(n-propyloxy)-4-(tert-butoxycarbonyl)biphenyl was obtained in the same manner as in the Example 104.
