Yield: 80.1%
Reaction Conditions:
with acetic acid;Selectfluor in acetonitrile at 80; for 24 h;
Steps:
82.1 Step 1: Preparation of 2,4-dicMoro-5-fluoro-7H^yrrolo[2,3-d]pyrimidine
After 2,4-dicMoro-7H-pyrrolo[2,3-d]pyrimidine (200 mg, 1.06 mmol) was dissolved in acetonitrile (5.0 mL), l-chloromethyl-4-fluoro-l,4-diazoniabicyclo[2.2.2]octane bis(tetrafluoroborate) (561.6 mg, 1.6 mmol) and acetic acid (1 mL) were added thereto. The mixture was heated at 80 °C and stirred for 24 hours, and then the organic layer was isolated, treated with magnesium sulfate, filtered and then concentrated under reduced pressure. The residue was isolated by column chromatography to obtain a title compound (170.0 mg, yield: 80.1%). (0795) NMR (500MHz,CD3OD) δ 7.36(s, 1H)
