This compound has unique chemical properties. The synthetic route is as follows.
Example 26i 4-Bromo-2-(difluoromethoxy)pyridine 4-Bromopyridin-2(1H)-one (200 mg, 1.15 mmol) and sodium 2-chloro-2,2-difluoroacetate (210 mg, 1.38 mmol) were slurried in dry acetonitrile (8 mL). The mixture was refluxed overnight, allowed to cool to r.t. and directly extracted with pentane (3*5 mL). The combined organic phases were evaporated to give 219 mg (85% yield) of the title compound: 1H-NMR (500 MHz DMSO-d6) delta 8.18 (d, 1H), 7.70 (t, 1H), 7.56 (d, 1H), 7.50 (s, 1H); MS (CI+) m/z 226 224 [M+1]+
