Reaction Steps

4N solution of hydrogen chloride in dioxane (0.11 mL; 0.45 mmol) was added to a stirred solution of 4-[2-(benzyloxy)-4-fluorophenyl]-2-chloro-5-fluoropyrimidine (150 mg; 0.45 mmol) and 3-{[(2-methoxyethyl)sulfonyl]methyl}aniline (155 mg; 0.68 mmol; UkrOrgSynthesis Ltd.) in 1-butanol (1.0 mL). The batch was stirred at 140° C. for 60 hours. After cooling the batch was diluted with ethyl acetate and sodium bicarbonate solution. The organic phase was filtered using a Whatman filter and concentrated. The residue was purified by preparative HPLC to give the desired product (19 mg; 0.04 mmol).
