Reaction Steps

Aqueous TFA (90%) was added to a mixture of 4-[2-(2-methylprop-1-enyl)-1-ethylimidazol-5-yl]-2-{4-[N-(2-methoxyethyl)-N-t-butylsulphamoyl]anilino}pyrimidine (Method 111; 70 mg, 0.14 mmol), and anisole (90 μl, 0.83 mmol), and the mixture stirred at ambient temperature for 1 hour. The volatiles were evaporated and the residue dissolved in water. The solution was neutralised (NaHCO3), and extracted with EtOAc. The extracts were dried, and the solvent evaporated to give the title compound (30 mg, 41%).
