With dmap; 1-ethyl-(3-(3-dimethylamino)propyl)-carbodiimide hydrochloride; In dichloromethane; at 20.0℃; for 6.0h; | General procedure: A solution of 2-(2-methyl-1H-indol-1-yl)ethanamine (4a) (65 mg, 0.373 mmol) and 4-(piperidin-1-yl)benzoic acid (5) (76 mg, 1 eq.), and dimethylaminopyridine (catalytic, ?5 mg) in dichloromethane (6 mL) was added 1-ethyl-3-(3-dimethylaminopropyl)-carbodiimide.hydrochloride (EDCI) (92 mg, 1.3 eq.) at room temperature. The resulting reaction mixture was stirred for 6h. At the conclusion of the reaction (TLC), water (15 mL) was added to quench the reaction. The product was extracted with ethyl acetate (20mL×3). Organics were washed with dilute HCl (10 mL), saturated NaHCO3 solution (10 mL), water (10 mL) and brine solution (10 mL) and dried over Na2SO4 and concentrated. The resulting crude product was subjected to silica gel chromatography eluting with 0-40% ethyl acetate in hexane to furnish 7k (TG7-152) (100mg, 74% yield). 1H NMR (CDCl3): delta 7.52 (d, J=5.6Hz, 1H), 7.49 (d, J=8.8Hz, 2H), 7.30 (d, J=8Hz, 1H), 7.07 (m, 2H), 6.80 (d, J=8.2Hz, 2H), 6.23 (s, 1H), 5.98 (t, J=5.4Hz, 1H), 4.33 (t, J=6Hz, 2H), 3.76 (q, J=6Hz, 2H), 3.25 (t, J=4.8Hz, 4H), 2.37 (s, 3H), 1.6 (m, 6H). LCMS (ESI): >97% purity at lambda 254, MS; m/z, 362 [M+H]+. Anal. Calcd. for C23H27N3O: C, 76.42; H, 7.53; N, 11.62; found; C, 76.48; H, 7.55; N, 11.59. |
