Sulfuric acid magnesium salt (1:1) → [(6-Chloro(3-pyridyl)methyl][(4-methoxyphenyl)methyl]amino}ethan-1-ol

Participants

Reaction Steps

This compound was prepared in a manner analogous to that of Step A of Example 1, using 4.9 grams (0.026 mole) of 2-{[(6-chloro-3-pyridyl)methyl]amino}ethan-1-ol, 3.6 grams (0.026 mole) of 4-methoxybenzaldehyde, 8.3 grams (0.039 mole) of sodium triacetoxyborohydride and 5.8 grams (0.052 mole) of magnesium sulfate in 200 mL of 1,2-dichloroethane. The crude product was purified with column chromatography on silica gel. Elution was accomplished using 100% methylene chloride and 100% diethyl ether as eluants. The appropriate fractions were combined and concentrated under reduced pressure, yielding 9.3 grams of the subject compound. The NMR spectrum was consistent with the proposed structure.
