Reaction Conditions

Reaction Steps

To a suspension of 2-chloro-7H-pyrrolo[2,3-d]pyrimidine (700 mg, 4.33 mmol) in BuOH (10 mL) is added 4-isopropoxyaniline (1.31 g, 8.66 mmol) and concentrated aqueous HCl (37%, 1.28 mL, 13.0 mmol). The reaction mixture is heated to 140° C. for 24 h, cooled to rt, and concentrated under reduce pressure. The residue is dissolved in 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 solid residue is triturated with hexane to yield the title compound as an off-white solid.
