Reaction Steps
(R)-8-Fluorochroman-4-amine (60 mg) was added to a solution of 2,4-dichloro-5-nitropyrimidine (70 mg) and DIEA (0.14 mL) in THF (5 mL) at −78° C. The reaction mixture was stirred for a further 15 min at −78° C. then removed from the cold bath and allowed to warm to RT. A one molar solution of the sodium salt of benzimidazole (0.7 ml, stock solution prepared via the addition of sodium hydride to a benzimidazole solution in THF) was added to the reaction intermediate ((R)-2-chloro-N-(8-fluorochroman-4-yl)-5-nitropyrimidin-4-amine) and the resulting mixture was stirred at RT overnight. Purification via column chromatography (elution with MeOH/DCM) gave the titled compound (120 mg), MH+=407.
