Procedure

A stirred solution of 0.2 gram (0.0001 mole) of 4-(2-(diethylamino)ethoxy)benzaldehyde (prepared in the manner of Step A, Example 3), 0.22 gram (0.0001 mole) of 1-amino-4-chloronaphthalene (available from Aldrich Chemical Company), and one drop of p-toluenesulfonic acid monohydrate (available from Aldrich Chemical Company) in 5 mL of toluene was heated at reflux for ten hours. At the conclusion of this period, the reaction mixture was concentrated under reduced pressure, yielding a residue. The residue was taken up in 5 mL of methanol and about 0.2 grams (0.004 mole) of sodium borohydride was added. The resulting mixture was stirred at ambient temperature for about 18 hours. After this time, the mixture was quenched with water and extracted with several portions of diethyl ether. The extracts were combined, dried with sodium sulfate and filtered. The filtrate was concentrated under reduced pressure, yielding 0.8 gram of Compound 84. The NMR spectrum was consistent with the proposed structure.
