Reaction Steps

2,4-Dichloro-5-iodo-7-((2-(trimethylsilyl)ethoxy)methyl)-7H-pyrrolo[2,3-d]pyrimidine (1 equiv), cyclopentanamine (1 equiv), sodium tert-butoxide (7.5 equiv), and 1,4-dioxane (0.28 M) were combined in a sealable vessel with a stir bar. The resulting mixture was put under nitrogen atmosphere, sealed, stirred vigorously, and heated at 70° C. After cooling to room temperature, the reaction mixture was loaded directly onto a silica gel column and purified using flash chromatography (Biotage) (0-20% ethyl acetate in hexane) to give the title compound (94% yield) as a yellow solid. MS (ESI) m/z 493.2 [M+1]+.
