thank you for your suggestions.
I have also thought of the possibility to carry out a direct Friedel-Craft reaction between 2,6-diphenyl phenol and 4-methoxy benzylchloride. In my opinion, that would be the shortest way to get the alcohol number 2. If you also do not think there will be problems with the regioselectivity (because the positions ortho to the phenyl rings are quite hindered, on the other hand, the phenol is para dirigating and the central ring is the most activated), it is worth to do try.
The use of 4-methoxybenzoyl chloride (50 ml/30Euro) under Friedel-Crafts conditions to get the benzophenone and reduce the ketone is also an idea. It is, however, one more step to do.
