Procedure

Synthesized from pivalic acid 6-(2-ethylamino-4-methoxyphenyl)-5,6,7,8-tetrahydronaphthalen-2-yl ester and 4-(2-dimethylamino-2-methylpropoxy)benzaldehyde according to an analogous synthetic method to Example 212, to a solution of the resulting pivalic acid 6-{2-{[4-(2-dimethylamino-2-methylpropoxy)benzyl]ethylamino}-4-methoxyphenyl}-5,6,7,8-tetrahydronaphthalen-2-yl ester (73 mg) in tetrahydrofuran (1.5 ml) was added lithium aluminum hydride (20 mg), and the solution was stirred for 1.5 hours at room temperature. Tetrahydrofuran and aqueous ammonia were sequentially added thereto followed by stirring. The solution was then filtered through celite pad, the resulting residue was purified by NH silica gel column chromatography (ethyl acetate-methanol system) to provide the title compound (45 mg).
