Benzaldehyde → 3-(3-(Benzylamino)phenyl)-3-hydroxypropanenitrile

Participants

Reaction Steps

NaBH(OAc)3 (7.84 g, 36.99 mmol) was added to a solution of aniline 12 (2.0 g, 12.33 mmol) and benzaldehyde (1.3 g, 12.33 mmol) in DCM. The resulting mixture was stirred at RT for 5 h and quenched with saturated aqueous NaHCO3. Organic layer was washed with water followed by brine and dried over anhydrous Na2SO4. Organic layer was concentrated under reduced pressure. Purification by flash chromatography (40% to 50% EtOAc—hexanes gradient) gave 3-(3-(benzylamino)phenyl)-3-hydroxypropanenitrile as a pale yellow oil. Yield (2.61 g, 83%); 1H NMR (400 MHz, DMSO-d6) δ 7.36-7.29 (m, 4H), 7.23-7.19 (m, 1H), 6.99 (t, J=8.0 Hz, 1H), 6.68 (s, 1H), 6.54 (d, J=7.6 Hz, 1H), 6.44 (dd, J=1.6, 8.0 Hz, 1H), 6.27 (t, J=6.0 Hz, 1H), 5.79 (d, J=4.4 Hz, 1H), 4.72-4.68 (m, 1H), 4.25 (d, J=6.0 Hz, 2H), 2.82-2.67 (m, 2H).
