Procedure
Following a procedure similar to that described in Example 49(i), but using 1-(4-fluorophenyl)-4-hydroxymethyl-5-methyl-2-(4-methylsulfonylphenyl)pyrrole (prepared as described in Example 47) and manganese dioxide as starting materials, the title compound was obtained as a white powder (yield 98%), melting at 167-169° C.
