실험 절차

To a solution of (5-chloro-pyridin-2-ylsulfanyl)-acetic acid (15, 0.27 g, 1.3 mmol) in dry CH2Cl2 (10 mL) and DMF (2 mL) at 0° C. was added HATU (0.5 g, 1.3 mmol) and reaction mixture was stirred for 30 min at ambient temperature. Then the reaction mixture was cooled to 0° C. and neat 8-methyl-1,2,3,4-tetrahydroquinolin (0.20 g, 1.3 mmol) was added via syringe followed by addition of DIPEA, (0.69 mL, 3.9 mmol). The reaction mixture was allowed to warm to room temperature over 18 h. The reaction mixture was diluted with 50 mL of CH2Cl2, washed with H2O, 10% citric acid, NaHCO3 (saturated), brine, dried over Na2SO4 and concentrated. The crude was purified by column chromatography (hexanes/EtOAc) to give 90 mg of the target 16 as a white solid in 20% yield. MS (APCI) m/z: 333.1 (100%, [M+H]+, 186.0 (20%, [M−147+H]+; HPLC purity: 100%; Anal. Calcd. for C17H17ClN2OS: C, 61.34; H, 5.15; N, 8.42; Cl, 10.65; S, 9.63. Found: C, 61.33; H, 5.06; N, 8.36; Cl. 10.67; S, 9.56.
