実験手順

A homogeneous mixture of 6-amino-2-(tert-butylcarbonyl)amino-3-methoxypyridine (35) (1.5 g, 6.72 mmol) and 2,4-dichloro-5-fluoropyrimidine (53) (1.68 g, 10 mmol) in methanol:water (20 mL, each) was stirred at 60° C. for 48 hours. The reaction mixture upon dilution with water (100 mL) gave a solid, which was isolated by filtration to obtain N4-[2-(tert-butylcarbonyl)amino-3-methoxypyrid-6-yl]-2-chloro-5-fluoro-4-pyrimidineamine. LCMS: purity: 89%; MS (m/z): 354 (MH+).
