Versuchsvorschrift

To a 0.33 M solution of 4-(dimethylamino)benzaldehyde in THF at 0° C. was added 1.1 equiv of 4-isopropylaniline followed by 1.5 equiv of sodium triacetoxyborohydride. After allowing the reaction to warm to room temperature overnight, this mixture was poured into a separatory funnel containing aqueous NH4Cl/EtOAc. The organic layer was washed with brine, dried over anhydrous Na2SO4, filtered and concentrated. The crude material was further purified by flash chromatography, eluting with a gradient from 100% hexanes to 10% EtOAc/hexanes to provide the title compound as a white solid.
