Yield:14321-27-8 94.9%

Reaction Conditions:

Stage #1: benzyl aldehyde;ethylamine in methanol at 20;
Stage #2: with sodium tetrahydridoborate in methanol; for 6 h;

Steps:

General procedure for the preparation of compounds 7a-d.

General procedure: To a mixture of benzaldehydes (10 mmol) in methanol (20 mL), the methylamine or ethylamine(10 mmol) was added. The reaction mixturewas stirred at room temperature for 3-4 h, and then sodium borohydride (5.0mmol) was added in batches and the mixture was further stirred for anotherperiod of 6 h. The reaction was then quenched by the addition of water (10 mL),and washed with diethyl ether (20 mL× 3). The combined organic phases werewashed with saturated aqueous NaCl (30 mL), dried over Na2SO4,and filtered. The solvent was evaporated to dryness under reduced pressure. The residue was purified on a silica gel chromatography usingmixtures of CH2Cl2/CH3OH as eluent to obtainthe light yellow oil 7a-d.
