Abstract The rearrangement of benzyl phenolic ether in the presence of an acid or AlCl3 is utilized to produce biphenyl methane compounds in very good yields. The synthesis of muscarine receptor antagonist tolterodine is described.

We have developed a new and straightforward synthesis of racemic tolterodine [ N, N-diisopropyl-3-(2-hydroxy-5-methyl-phenyl)-3-phenylpropanamine]. The synthesis involves selective nosylation on the primary alcohol of 1-phenylpropane-1,3-diol using 4-nitrobenzenesulfonyl chloride, subsequent diisopropylamine substitution, and Friedel-Crafts alkylation using aqueous perchloricacid.
