Reaction Steps

5-[2,6-Difluoro-4-(1-hydroxy-1-methylethyl)phenyl]-2-[(6-oxo-1,6-dihydropyridazin-3-yl)amino]thiophene-3-carboxamide (Example 578 Step 3) (50 mg, 0.12 mmol), K2CO3 (18.70 mg, 0.14 mmol) and methyl bromoacetate (0.012 mL, 0.13 mmol) were stirred in DMF (1 mL) at 80° C. overnight. The reaction mixture was cooled to room temperature, water was added and the reaction mixture was extracted into EtOAc (×2). The combined organic extracts were washed with brine, dried over MgSO4, filtered, and concentrated in vacuo. Purification of the residue by silica gel column chromatography (0-15% MeOH—CHCl3) gave the title compound as a yellow solid after triturating in DCM.
