Friedel-Crafts acylation of toluene (II) with 3-methoxybenzoyl chloride (I) gave benzophenone (III). Subsequent methyl group oxidation using KMnO4 afforded carboxylic acid (IV), which was further converted to amide (V) by activation with SOCl2, followed by treatment with diethylamine. Reduction of the keto group of (V) by means of NaBH4 yielded alcohol (VI). The required benzhydryl chloride (VII) was then prepared by treatment of alcohol (VI) with concentrated HCl.
