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, 0.123 mmol), K2CO3 (18.70 mg, 0.135 mmol) and iodomethane (8.08 μL, 0.129 mmol) were stirred in DMF (1 mL) at 80° C. overnight. The reaction mixture was cooled to room temperature, water was added and the products extracted into EtOAc (2×). The combined organic extracts were washed with brine, dried over MgSO4 and concentrated in vacuo. Purification of the residue twice by silica gel column chromatography (0-10% MeOH—CHCl3) followed by mass-triggered reverse phase HPLC gave the title compound as a yellow solid.
