Reaction Steps

To a solution of 3-(2-Fluoro-4-iodo-phenylamino)-isonicotinic acid hydrazide (300 mg; 0.81 mmol; 1 eq) in DCM (5 mL), 1-(2-Isothiocyanato-ethyl)-piperidine (192 mg; 1.13 mmol; 1.4 eq) was added. The reaction mixture was refluxed for 4 hrs under argon. A yellow solid precipitated out and filtered to afford an intermediated that was suspended in ethanol (5 mL). Iodomethane (148 mg; 1.05 mmol; 1.3 eq) was added to the reaction mixture and stirred overnight at RT, then heated to 80° C. and stirred for another 2 hr. The mixture was filtered to give a yellow solid product 40 mg. LC/MS (Method A) [3.89 min; 509(M+1)]
