Reaction Steps
A mixture of 2-(N-n-propylamino)-5-methoxytetralin, 2-benzothienyl acetic acid and trimethylaminoborohydride in dry xylene is refluxed under an atmosphere of nitrogen as described by Horn et al, Pharm. Weekbld. Sci. Ed. 7 208-211, 1985. The resulting methoxy intermediate is demethylated using boron tribromide as described in the above article to yield the desired product.
