To a reaction vial with 4-(1-Amino-3-methyl-butyryl)-benzoic acid ethyl ester (2) (440 mg, 1.9 mM) was added DMSO (6.33 mL), 3-bromo-7-methylquinoline (9) (420 mg, 1.9 mM), followed by Cul catalyst (36 mg, 0.19 mM) and CsOAc (726 mg, 3.78 mM). The mixture was purged with argon gas and then the tube was sealed. The reaction mixture was heated to 100° for 48 h. The reaction mixture was cooled, diluted with EtOAc (10 mL), washed with water (3×5 mL), dried (Na2SO4) and concentrated. The crude material was separated by a 40 g silica gel with 0-80% EtOAc in heptane to give a yellow color product (108 mg, 15%). 1H NMR (500 MHz, CDCl3) δ ppm 0.98 (d, J=6.34 Hz, 3H) 1.04 (d, J=6.34 Hz, 3H) 1.39 (t, 3H) 1.61-1.71 (m, 1H) 1.71-1.86 (m, 2H) 2.46 (s, 3H) 4.36 (q, 2H) 4.38-4.43 (m, 1H) 4.47-4.56 (m, 1H) 6.75 (d, J=1.95 Hz, 1H) 7.20 (d, J=8.29 Hz, 1H) 7.36 (d, J=8.05 Hz, 1H) 7.47 (d, J=8.29 Hz, 2H) 7.69 (s, 1H) 8.03 (d, 2H) 8.47 (br. s., 1H). LC-MS: m/z 377.2 (M+1).
