Procedure

To a solution of 2-chloro-6-(4-ethylphenyl)-3-(trifluoromethyl)pyridine (Example 315, 0.36 g, 1.25 mmol) and 3-amino-1-propanol (0.38 g, 5.00 mmol) in CH3CN (2 mL), TFA (0.5 mL) was added. The mixture was stirred at reflux for 18 h, and then concentrated under reduced pressure. The product (0.21 g, 52%) was isolated after silica gel flash chromatography (2:1 hexanes/EtOAc). 1H NMR (400 MHz, CD3OD) δ 7.95 (d, 2H), 7.72 (d, 1H), 7.27 (d, 2H), 7.10 (d, 1H), 3.72 (t, 2H), 3.66 (t, 2H), 2.69 (q, 2H), 1.90 (q, 2H), 1.27 (t, 3H).
