Reaction Steps
To a solution of (R)-1-(4-bromophenyl)-2,2,2-trifluoroethanol (150 mg, 0.60 mmol) in dioxane (10 mL) was added 4,6-dichloropyrimidin-2-amine (120 mg g, 0.71 mmol) and Cs2CO3 (290 mg, 0.88 mmol), and the reaction mixture was heated to 80° C. for 30 h. Then the reaction was cooled to RT. EtOAc was added and the organic layer was washed with brine, dried over Na2SO4, filtered, and concentrated in vacuo. Purification by normal phase silica gel column (EtOAc/heptane) provided (R)-4-(1-(4-bromophenyl)-2,2,2-trifluoroethoxy)-6-chloropyrimidin-2-amine as a colorless oil.
