Reaction Steps

In a sealed tube, 2-chloro-7H-pyrrolo[2,3-d]pyrimidine (200 mg, 1.24 mmol), 4-(4-bromo-2,6-difluoro-benzyl)-morpholine (418 mg, 1.36 mmol), CuI (72.1 mg, 0.371 mmol), and K3PO4 (804 mg, 3.71 mmol) are suspended in 1,4-dioxane (8 mL). Then, trans-1,2-diaminocyclohexane (45.0 μL, 0.371 mmol) is added at rt. The reaction vial is flushed with Ar and the mixture is heated to 110° C. for 5 h. After cooling to rt, the reaction mixture is diluted with EtOAc and the organic layer is washed with saturated aqueous Na2CO3 solution (2×). The organic layer is dried over Na2SO4, filtered, and concentrated under reduced pressure. The residue is purified by column chromatography (SiO2, gradient elution, hexane/EtOAc 100:0→30:70) to yield the title compound as a white solid.
