Procedure

A mixture of (S)-(−)-3-chloro-1-phenyl-1-propanol (0.426 g, 2.50 mmol, 99% ee), 2-methyl-N-[3-(4-piperidinyl)phenyl]propanamide (0.565 g, 2.00 mmol), diisopropylethylamine (1.29 g, 10.0 mmol), dioxane (5.0 mL) and catalytic amount of tetrabutylammonium iodide was stirred at 90° C. for 72 hrs. Chromatography using silica preparative TLC plates [2.5% of NH3 (2.0 M in methanol) in CHCl3] gave the desired product (306 mg, 39.3% yield) as a thick oil: 1H NMR (400 MHz, CDCl3) δ 7.46 (S, 1H), 7.42 (d, 4H, J=3.1 Hz), 7.35 (m, 1H), 7.30 (d, 1H, J=8.0 Hz), 7.23 (t, 1H, J=8.1 Hz), 7.12 (s, 1H), 6.96 (apparent dd, 1H, J=8.0 Hz), 5.0 (apparent dd, 1H, J=4.4, 8.3 Hz), 3.18 (apparent dd, 2H, J=2.5, 12.5 Hz), 2.74 (m, 2H), 2.50 (m, 2H), 2.3–2.1 (m, 6H), 1.8 (m, 2H), 1.25 (d, 6H, J=7.1 Hz); ESMS m/e: 389.2 (M+H)+.
