Versuchsvorschrift

A solution of 4-(4-chlorophenoxy)benzaldehyde (0.119 g, 0.510 mmol) and 2-methyl-N-[3-(4-piperidinyl)phenyl]propanamide (0.126 g, 0.510 mmol) in 1,2-dichloroethane (5.00 mL) was treated with sodium triacetoxyborohydride (0.424 g, 2.00 mmol) and HOAc (0.0300 mL, 0.500 mmol) at room temperature. The mixture was stirred overnight at room temperature. The reaction mixture was neutralized with saturated NaHCO3 aqueous solution (10 mL) and the aqueous layer was extracted with CH2Cl2 (3×10 mL). The combined organic layers were washed with brine, dried over MgSO4, concentrated in vacuo and purified by preparative TLC plates using 5% of NH3 (2.0 M in methanol) in CH2Cl2 to give the desired product (53.0 mg, 23.0%): 1H NMR (400 MHz, CDCl3) δ 7.50 (s, 1H), 7.34–7.19 (m, 7H), 6.98–6.87 (m, 5H), 3.50 (s, 2H), 2.98 (d, 2H, J=11.8 Hz), 2.58–2.44 (m, 2H), 2.10–1.98 (m, 2H) 1.83–1.76 (m, 4H), 1.24 (d, 6H, J=6.8 Hz); ESMS m/e: 463.2 (M+H)+.
