실험 절차

A solution of 3-methylsulfanyl-propionyl chloride (120 mg, 0.9 mmol) in DCE (1 mL) was pipetted at a dropwise rate into an ice-cold suspension of methyl-(2-pyridin-3-yl-thiazol-5-yl)-amine (114 mg, 0.6 mmol) in DCE (5 mL), and the mixture was stirred for 5 min before adding a solution of DMAP (80 mg, 0.6 mmol) in DCE (1 mL). The ice bath was removed after 30 min, and the mixture was stirred at reflux under nitrogen for 15 min. The reaction mixture was cooled, diluted with DCE (70 mL), washed with saturated aqueous NaHCO3 (50 mL), dried over MgSO4 and purified by silica gel chromatography (3:1 ethyl acetate/hexanes) to afford a fine yellow powder (131 mg, 75%): mp 116-118° C.; 1H NMR (400 MHz, DMSO-d6) δ 9.08 (d, J=2.0 Hz, 1H), 8.61 (dd, J=4.8, 1.4 Hz, 1H), 8.24 (dt, J=9.8, 1.8 Hz, 1H), 7.81 (s, 1H), 7.51 (dd, J=7.7, 4.7 Hz, 1H), 3.56 (s, 3H), 3.02 (t, J=7.0 Hz, 2H), 2.76 (t, J=7.2 Hz, 2H), 2.12 (s, 3H); ESIMS m/z 294 (M+1).
