Using a procedure similar to that described in example 1 except starting with 1-(9,10-dihydro-9,10-methanoanthracen-9-ylmethyl)-4-piperidinone (described in example 5d) and employing 3,5-dibromo-2-methoxypyridine (literature preparation: J. M. Barger, J. K. Dulworth, M. T. Kenny, R. Massao, J. K. Daniel, T. Wilson, R. T. Sargent J. Med. Chem. 1986, 29, 1590), the title compound was formed in 63% yield as an off-white solid, mp 250°-251° C.
