실험 절차

To a solution of 3-(2-Fluoro-4-iodo-phenylamino)-isonicotinic acid hydrazide (500 mg; 1.34 mmol; 1 eq) in DCM (5 mL) 4-(3-Isothiocyanato-ethyll)-morpholine (255 mg; 1.61 mmol; 1.2 eq) was added. The reaction mixture was refluxed for 4 hrs under argon. A yellow solid precipitated out, which was filtered to afford an intermediate that was suspended in ethanol (5 mL). Iodomethane (190 mg; 1.34 mmol; 1.0 eq) was then added and the reaction mixture was stirred overnight at RT. It was then heated to 80° C. and stirred for another 2 hr. Filtration afforded the yellow solid product 153 mg. LC/MS (Method A) [0.41 min; 511(M+1)]
